Java 11 support #125

Closed Mulgish closed 5 years ago

Mulgish commented 5 years ago

Can KumuluzEE be compiled into Java 11?

Regards, Juri

jmezna commented 5 years ago

Yes, you have to use KumuluzEE 3.0.0

Mulgish commented 5 years ago

kumuluzee-microProfile-1.2 has jetty 9.4.11 dependency which does not seem to support java 11. Java 11 support was introduced in 9.4.12 (https://www.eclipse.org/lists/jetty-announce/msg00124.html).

I am getting the below error when my server bytecode level is 11. There are no problems with java 10 or 9.

This issue is caused by dependencies in MicroProfile 1.2. While KumuluzEE 3.0.0 and its components are Java 9+ compatible, not all extensions have been adjusted for Java 9 changes.

We are in the process of adjusting extensions for Java 9+, but until then, you can use KumuluzEE 3.0.0 with extensions on Java 1.8 or KumuluzEE 3.0.0 with only components and currently supported extensions on Java 11.
