Compile bug with javac

[XuPengfei-1020]

I get this error after I set javac as compiler.
And compile can not be finished correctly.

Looks like its happening at https://github.com/eclipse-jdtls/eclipse-jdt-core-incubator/blob/3d3f6fc78f42c66d670a3ecb1bd5a5d9edf1aa26/org.eclipse.jdt.core/model/org/eclipse/jdt/internal/core/builder/AbstractImageBuilder.java#L612 .

I guess this could happen if the bundle just failed to start correctly due to dependencies.

Would you be able to temporarily add "java.trace.server": "verbose", relaunch to reproduce the error and then attach the contents of Java: Open Java Language Server Log File .

It look like a network issue, What is the destination that 'published gradle version' download from? May be I can proxy it with VPN and try again.

This should be fixed in the pre-releases now.
