Selecting Java 11 for versions >3.0.0 downloads a Java 17 version.

[jmahicks]

Good day,

I am trying to download 3.1.2 in Java 11, but I get the following error message after I change the version in pom.xml to "11" from "17", even after specifying "Java 11" on the page:

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/springframework/boot/SpringApplication has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0

It seems that even when specifying the version as Java 11, version 3.1.2 and 3.0.9 are compiled in Java 17.

$ grep "version>" pom.xml | grep -v SNAPSHOT
		<version>3.1.2</version>
		<java.version>17</java.version>

$ grep "version>" pom.xml | grep -v SNAPSHOT
		<version>3.0.9</version>
		<java.version>17</java.version>

Version 2.7.14 is in Java 11.

$ grep "version>" pom.xml | grep -v SNAPSHOT
		<version>2.7.14</version>
		<java.version>11</java.version>

Are versions >3.0.0 only compiled in Java 17? It would seem so because even the build.gradle file shows sourceCompatibility = '17'.

Can the Java version radio buttons be disabled if that version of Java is unsupported in the currently selected Spring Boot version?

Yes. Spring Boot 3 requires Java 17 at a minimum.

Can the Java version radio buttons be disabled if that version of Java is unsupported in the currently selected Spring Boot version?

This is a duplicate of #1041.
