Re: GWT compilation error with JDK 11

GWT 2.9 should support running on Java 11, both running on JDK 11 and compiling Java 11 sources.

Without other information, it sounds like there is a problem with your copy of gwt-dev.jar - the jar might be corrupt, or somehow not on your classpath?

Can you verify that the jar is present and correct, and share more specifics of how you are building?

BTW, the Eclipse version is  Version: 2020-06 (4.16.0). 

Please help shed some lights on this issue.
