Hello,

We have an application can not compile using GWT-2.9 with JDK 11 after upgraded from GWT 2.5 and JDK 8.

It would be great if you can help shed some light on this. Please see below for the error:

At this line in JdtCompiler, the warningThredshold field is part of a JDT class, so double check your dependencies, your probably have an incompatible JDT/ECJ dependency in your classpath.
