Changelog

Noteworthy changes to the agent are documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Version 8.16.0

New features and improvements

  • Obfuscate JVM properties 2114 The Java agent will now obfuscate values passed to JVM properties. For example: -Dprop=12345 will now be sent as -Dprop=obfuscated. The documentation has information on how to disable obfuscation and how to add exceptions.

  • Cloud API 2081 The Cloud API allows cloud provider account information to be provided to the agent. This will allow the agent to populate the cloud.resource_id attribute in calls to select cloud services. The API documentation has information on how to use it programmatically. This information can also be provided using a configuration option.

  • Support distributed tracing for Kafka Stream 3.7.x 2095

  • Report if agent was installed via Azure site extension 2094

  • Lazy initialization of GUIDs on DefaultTracers 2088

  • Java HttpClient: Addition of status code to reported externals 2089

  • AWS Lambda: populate cloud.resource_id using data from Cloud API 2115

Version 8.10.0

⚠️ CAUTION: This agent version introduced a bug that may cause significant increases in CPU and memory usage and potential deadlock if your application uses HttpUrlConnection (or any libraries that use it under the hood). This issue has been resolved in the 8.11.0 agent. Alternatively, disabling the HttpUrlConnection instrumentation would prevent the issue (for example -Dnewrelic.config.class_transformer.com.newrelic.instrumentation.httpurlconnection.enabled=false).

PLEASE NOTE: Disabling this instrumentation will result in external calls made by the client no longer getting recorded. We strongly recommend using the latest agent versions, which include all recent code fixes and provide access to the latest platform features.

Version 8.9.0

New features and improvements

  • Instrumentation for Spring Webclient 5/6 now captures http status code and http status message 1658
  • Add status code to grpc-1.40.0 client instrumentation 1673
  • Add config to set the size limit of attributes on custom events (i.e. newrelic.config.custom_insights_events.max_attribute_value). Default size is 255 characters and the max is 4095. 1683
  • Add Spring instrumentation modules to support proper transaction naming (route + HTTP method) of traditional annotated spring controllers as well as controllers that inherit annotations from interfaces, super classes or custom annotations. Note that because the new instrumentation can change transaction names, enabling this "enhanced transaction naming" is gated by the newrelic.config.class_transformer.enhanced_spring_transaction_naming agent configuration option, which is false by default. Thanks to @mgr32 for their help with validating the naming changes. 1675
  • Add instrumentation for Vert.x 4.5.x web client and futures 1704

Fixes

  • Remove erroneous printing of stack trace in SlowTransactionManager 1684

Removals

  • Remove support for setting agent config with rarely used lower-case, dotted environment variable names (e.g. newrelic.config.labels). Customers relying on lower-case, dotted environment variables should switch to the standard upper-case, underscore names (e.g. NEW_RELIC_CONFIG_LABELS). There are no changes to documented system property behavior (via newrelic.config., server-side config, YAML, or standard environment variable (via NEW_RELIC_). 1598

Deprecations

  • The browser footer injection APIs have been deprecated and will be removed in a future agent release. The header injection API now adds both the header and footer scripts. 1679

  • aws-wrap-0.7.0
  • java.completable-future-jdk8
  • play-2.3
  • spring-3.0.0
  • netty-3.4
  • Struts v1

Version 8.8.0

New features and improvements

  • Add support for Jetty 12, including Jetty’s implementation of the Jakarta EE 8, 9, and 10 specs. 1621

  • Add support for Vert.x versions 4.0.0 through 4.4.x 1588

  • Add instrumentation for graphql-java 21 1454

  • Instrument r2dbc-postgresql 0.9.2 till latest 1413

  • Reintroduce the legacy HTTP Attributes that were removed in v8.0.0 to support customers with alerts and dashboards that require them 1671 The attributes are:

    • httpResponseCode
    • httpResponseMessage
    • response.status
    • response.statusMessage

    Attribute reporting is configurable via the following means.

    YAML:

    attributes:
  http_attribute_mode: both

    System property:

    -Dnewrelic.config.attributes.http_attribute_mode=both

    Environment variable:

    NEW_RELIC_ATTRIBUTES_HTTP_ATTRIBUTE=both

    The configuration options are:

    • standard : The agent will send new standard attributes. This configuration is recommended but requires that any alerts or dashboards using attributes be updated to use these new attributes. This setting will reduce the amount of ingest used for attribute reporting.
    • legacy : The agent will send the legacy attributes referenced above. Customers with alerts or dashboard requiring these attributes can continue to be used as-is. This setting will reduce the amount of ingest used for attribute reporting.
    • both : This is the default configuration, the agent will send BOTH legacy AND standard HTTP attributes. This configuration was intended to support customers that are unable to modify their alerts or dashboards but this configuration will increase data ingest.

  • Add an interface for our error API. Our error API can now be called via the code NewRelic.getAgent().getErrorApi() 1577

  • Add log4j2 JsonLayout support and support log4j2 till latest. 1545

  • Add httpstatus in the external segment for Spring Webclient 1610

  • Enable slow transaction detection by default and bump the threshold to 10 minutes 1629

  • Add support for string formatting with JBoss Logging. 1650

  • Add logic to remove specific classes from being excluded from being weaved if the IAST security feature is enabled. 1453

    The affected classes belong in the following formats:

    • ^java/security/.*
    • ^javax/crypto/.* These are crypto classes which can cause class circularity errors if they get too far along in the class transformer.
    • ^net/sf/saxon.*

    If you wish to re-include these excluded rules, you can do so via the following means.

    YAML:

      class_transformer:
    excludes: ^javax/crypto/.*,^java/security/.*,^net/sf/saxon.*

    System property:

    -Dnewrelic.config.class_transformer.excludes=^javax/crypto/.*,^java/security/.*,^net/sf/saxon.*

    Environment variable:

    NEW_RELIC_CLASS_TRANSFORMER_EXCLUDES=^javax/crypto/.*,^java/security/.*,^net/sf/saxon.*

  • Prevent license_key value from being written to the agent logs when using debug and/or audit_mode logging 1653

IAST

  • The IAST feature now also supports Async HTTP client version 2 and above 142
  • Added support for Sun Net HTTP Server 142
  • JSON version bump to 1.1.1 142
  • Add critical error logging via LogMessage event 142

Fixes

  • Fix transaction naming in Spring controllers with a CGLIB proxy. Transactions now use the actual class name as opposed to the proxied class name. 1574

  • Fix a NullPointerException caused by ServletContext in servlet instrumentation modules. 1636

  • Fix a memory leak caused by Lettuce instrumentation. Duplicate code for transaction linking has been removed from the Lettuce instrumentation and is handled by netty-reactor instead. 1608

  • Fix a bug where invalidating a license key causes a memory leak. Reconnection tasks are now capped in the event of a LicenseException. 1606

  • Fix a NullPointerException caused by RPMServiceManager 1604

  • Add a workaround for a memory leak that may occur in rare scenarios with instrumentation using the legacy async API in the Java Agent (which async servlets and Jetty Continuations use). 1555

    The option can be configured via the following means:

    Agent config file (this will update dynamically if the config file is changed)

    common: &default_settings
  legacy_async_api_skip_suspend: true

    System Property

    -Dnewrelic.config.legacy_async_api_skip_suspend=true

    Environment Variable

    NEW_RELIC_LEGACY_ASYNC_API_SKIP_SUSPEND=true

IAST

  • DynamoDB v2 issue: missing attribute values for conditionCheck method in case of transactWriteItems operation on DynamoDB 142

  • Fixed an Insecure cookie attack vulnerability. 142

  • Never print LicenseKey 142

Deprecations

    • db.collection
    • server.address
    • server.port

    Removed attributes:

    • component
    • peer.hostname

  • Add slow transaction detection which can be configured. It is disabled by default. 1542 E.g:

    slow_transactions:
  enabled: true
  threshold: 1000 # The threshold is measured in milliseconds

  • Add instrumentation for r2dbc postgresql 0.9.2 to 0.9.x 1410

  • Security Agent: Add new configuration to enable/disable low priority instrumentation security.low-priority-instrumentation.enabled for the CSEC agent. Default value is false. 1515

  • Fix HttpUrlConnection instrumentation so segment timing is accurate 1537

  • Fixes a bug in Spring 6 instrumentation where transactions are incorrectly named in certain scenarios. 1544 Such include:

    • "built-in" controllers that don't have @RestController-like annotations, e.g. /actuator/health (see Actuator endpoints)
    • custom controllers that don't use @RestController directly (e.g. using custom annotations)
    • requests returning 401s / 404s

  • Add a fix for JBoss EAP / Wildfly where if customers are using the J2EE/Jakarta Management API, the application fails to startup. 1549 This is done by adding the system property com.newrelic.jboss.jsr77.fix and setting it to true. E.g.

    -Dcom.newrelic.jboss.jsr77.fix=true

    Customers using JBoss EAP 7.4+ or Wildfly 23+ will need to manually configure the io.undertow.servlet module and add java.management as a dependency. This translates to doing the following steps:

    1. Opening the file modules/system/layers/base/io/undertow/servlet/main/module.xml
    2. Adding the XML element <module name="java.management"/> inside the body of the <dependencies> tag

    Here is what the configured XML file may look like:

    <module name="io.undertow.servlet" xmlns="urn:jboss:module:1.9">
    <resources>
        <resource-root path="undertow-servlet-2.2.5.Final-redhat-00001.jar"/>
    </resources>

    <dependencies>
        <module name="javax.annotation.api"/>
        <module name="sun.jdk"/>
        <module name="javax.servlet.api"/>
        <module name="javax.servlet.jsp.api"/>
        <module name="javax.servlet.jstl.api"/>
        <module name="org.jboss.logging"/>
        <module name="io.undertow.core"/>
        <module name="org.jboss.xnio"/>
        <module name="jdk.unsupported"/>
        <module name="java.management"/>
    </dependencies>
</module>

Full Changelog: https://github.com/newrelic/newrelic-java-agent/compare/v8.2.0...v8.3.0

Version 8.2.0

New features and improvements

  • Added support for Java 20 #1226

Fixes

  • Prevented a NullPointerException from the lettuce instrumentation #1204

  • Fix failure with browser agent auto injection for tomcat versions 8.5.87+ and 9.0.74+ #1225

Full Changelog: https://github.com/newrelic/newrelic-java-agent/compare/v8.1.0...v8.2.0

Version 8.1.0

New features and improvements

  • Added support for Webflux 6 1181

  • Added support for Spring JMS 6 1088

  • Added support for Mongodb Reactive Streams 1164

  • Added support for Kafka Streams 1170

    Support for Kafka Streams comes in two flavors, metrics and spans. Metrics are enabled by default, while spans are disabled by default. To enable spans add the following to your newrelic.yml configuration under the common stanza:

common:
  class_transformer:
    kafka-streams-spans:
      enabled: true

  • Error fingerprint - supply your own errors inbox group names 1195

    Are your error occurrences grouped poorly? Set your own error fingerprint via a callback function. A new public API method has been added that will accept a user defined proc. The proc will be invoked for each noticed error and whenever it returns a string, that string will be used as the error group name for the error and will take precedence over any server-side grouping that takes place with the New Relic errors inbox. This gives users much greater control over the grouping of their errors. For more information check our API: Error Grouping and APM: Group errors tab pages.

  • User tracking 1188

    You can now see the number of users impacted by an error group. Identify the end user with a new public API method that will accept a string representation of a user id and associate that user id with the current transaction. Transactions and errors will then have a new enduser.id agent attribute associated with them. This will allow agent users to tag transactions and errors as belonging to given user ids in support of greater filtering and alerting capabilities. For more information check the [Newrelic.setUserId ](https://newrelic.github.io/java-agent-api/javadoc/com/newrelic/api/agent/NewRelic.html#setUserName(java.lang.String) documentation and the Track users impacted with errors inbox page.

Version 8.0.0 (2023-01-26)

Important

This release includes a change to the HttpURLConnection instrumentation that creates a TimerTask to help ensure complete externals reporting. Under some circumstances this may result in a large number of threads being created, which may exhaust the maximum allocated to the JVM, causing it to stop. This issue has been fixed in the 8.0.1 release and it is highly recommended that you update to this version of the Java agent.

New features and improvements

  • Added support for Slick 3.4.0 on Scala 2.13 #1072
  • Added support for Embedded Tomcat JMX #1039
  • Updated the Java agent’s snakeyaml dependency to 1.33 #1077

The agent can now forward data in Mapped Diagnostic Context (MDC, logback/slf4j) and ThreadContext (log4j2) as attributes when forwarding log records. When the feature is enabled, these attributes will be added to the log records with a context. prefix. For details on how to enable this feature see the documentation for context_data.

Custom Event Limit Increase 1036

This version increases the default limit of custom events from 10,000 events per minute to 30,000 events per minute. In the scenario that custom events were being limited, this change will allow more custom events to be sent to New Relic. There is also a new configurable maximum limit of 100,000 events per minute. To change the limits, see the documentation for max_samples_stored. To learn more about the change and how to determine if custom events are being dropped, see our Explorers Hub post.

Code-level metrics on by default 1037

The code-level metrics functionality introduced with agent 7.10 is now enabled by default. This feature will cause an increase in the consumption of data. The amount depends on the application. To disable code-level metrics, see instructions on our code-level metrics documentation.

Code level metrics

For traced methods in automatic instrumentation or from @Trace annotations, the agent is now capable of reporting metrics with method-level granularity. When the new functionality is enabled, the agent will associate source-code-related metadata with some metrics. Then, when the corresponding Java class file that defines the methods is loaded up in a New Relic CodeStream-powered IDE, the four golden signals for each method will be presented to the developer directly.

Agent log forwarding now adds the following attributes to log events for the log4j2 and logback1.2 frameworks:

thread.name thread.id logger.name logger.fqcn error.class error.stack error.message

Fixes

Fixed an issue with Distributed Tracing headers not being added on external requests made with the HttpUrlConnection client

Version 7.0.0 (2021-6-9)

New features and improvements:

  • Real-time profiling for Java using JFR metrics
    Real-time profiling for Java using JFR metrics is now fully integrated into the Java agent. See the JFR core README for additional details.

    This feature requires a supported version of Java (Java 8 (specifically version 8u262+) or Java 11+) and is currently disabled by default. To enable it set the following in your yaml (indented 2 spaces under the common stanza).

      jfr:
    enabled: true

    Notice: If you were previously using the jfr-daemon jar as an agent extension or standalone process you should remove that option to avoid potential conflicts with the JFR service that is now built into the agent.

  • Not compatible with Java 7
    In order to continue to innovate and efficiently provide new capabilities to our customers who run on the JVM, this and future agent versions are not compatible with Java 7. If you are running Java 7, you may continue to use Java agent 6.5.0 or lower. For details, see this topic on the Explorers Hub.

  • Adds support for akka http with Scala 2.13 #271

  • Class annotation to trace lambda methods #274

  • Class annotation to trace methods by return type #275
