Sample Spring app is broken in Jetty container

[HaloFour]

The version of Jackson currently used by the Spring sample project has an embedded module-info for Java 9 JMS which causes Jetty to throw an exception when scanning for attributes. We would need to upgrade to at least Jetty 9.4.x which has support for Java 9, even if we're running on a Java 8 runtime. I did attempt that upgrade last night but was having trouble getting the Spring mappings to work so that will require additional work. However, downgrading Jackson back to 2.9.x works around the issue.

See: jetty/jetty.project#1692

Looking at https://github.com/Comcast/money/blob/master/samples/samples-springmvc/pom.xml#L14

It references Jetty 8.x, which is EOL (End of Life) and should not be used.
Jetty 8.x is also subject to several security issues, be aware of them.
