Andriy Redko updated CXF-8074:
------------------------------
Description:
Ideally, the multi-release JARs have to be build with multiple JDKs, for
example if JDK is the latest one, pre-JDK13 and JDK13.
Or, alternatively, by latest JDK13 twice, once for {{src/main/java}} (using
{{--release 8-}}) and once for {{src/main/java13}} (equivalent to {{-release
13}}).
The issue is with {{tools.jar}}, which is not in scope of javac's
{{--release-}} flag [1], it really needs to be built by JDK8. As the
workaround, we could used {{-release 9}} to mitigate this issue (since
{{tools.jar}} was merged into JDK9+) in a short term. The long term solution
would be to use toolchain plugin.
