Xtext version working with Java 11 [message #1798974]

Hi,

Is there a version of xtext working with OpenJDK 11?

I tried with xtext 2.15 (released in September) but it seems not to support it yet. There is an exception coming from org.objectweb.asm library which doesn't understand java 11 (Unsupported class file major version 55).

Is xtext 2.16 going to be compatible with OpenJDK11? What is planned release date?

Thank You!

Cheers,
Dominik

You should be able to run Xtext 2.16 on Java 11 if you target for a lower version. Full J11 support is targeted for 2.17. We depend on too many components that are not all fully J11 supporting yet, and 2.16 release is already next week Dec 4th.
You can try to use the latest milestone 2.16.0.M3, which has been released monday. Feedback welcome. For the release, we will accept patches for bugs, but don't work on features anymore.

Hi

I have performed a successful Eclipse OCL build and test using Java 11. This includes Xtext editors and some fairly trivial automated edits that demonstrate that there is a plausible user editing experience available.

The latest platform builds have switched to ASM 7. Perhaps that is your problem.

Regards

Thanks! Indeed switch to 2.16.0.M3 enabled me to compile my projects under OpenJDK 11.
I have still some problems but these seems on my side.

One thing I needed to do was to disable web module - xtext.xbase.web 2.16.0.M3 depends on SNAPSHOT version of org.eclipse.lsp4j. Is there a repository that I could get it from? (I guess Maven Cental doesn't keep snapshots).

Cheers,
Dominik
