Add JDK 11 support #5909

commented Apr 26, 2019

This PR updates the server code base to support JDK 11.

This also requires updates to a few plugins due to the UUID changes.

There is a warning that is printed on server startup:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by$MethodHandleWrapper (file:/home/bernd/.m2/repository/com/google/inject/extensions/guice-assistedinject/4.2.2/guice-assistedinject-4.2.2.jar) to constructor java.lang.invoke.MethodHandles$Lookup(java.lang.Class,int)
WARNING: Please consider reporting this to the maintainers of$MethodHandleWrapper
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

Seems to be related to google/guice#1216 and google/guice#1133.

@bernd bernd added this to the 3.1.0 milestone Apr 26, 2019

Thanks for taking the time working on this - we're really looking forward to java 11 support.

Is this likely to make it into 3.1.0, since it's not included in the current beta release?

Add JDK 11 support
- Use our own fork of com.eaio.uuid:uuid which has been modified to work
  with JDK 11
- Add javax.xml.bind:jaxb-api dependency (fixes runtime dependency issue)
- Remove unused
- Fix duplicate key exception in LocalesResponse#create()

Compiles fine on macos with

java version "1.8.0_192"
Java(TM) SE Runtime Environment (build 1.8.0_192-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.192-b12, mixed mode)

Runs fine with

openjdk version "11.0.4" 2019-07-16
OpenJDK Runtime Environment (build 11.0.4+11-post-Debian-1deb10u1)
OpenJDK 64-Bit Server VM (build 11.0.4+11-post-Debian-1deb10u1, mixed mode, sharing)

Compiling with java 11 needs a bit more work.
I had to remove errorprone, forbiddenapis from the build.

@mpfz0r Thanks for testing! I think it's fine if we can run with JDK 11 for now. Building with it can be a separate step.
