Internal Compiler Failure when trying to upgrade a GWT 2.7.0 application to 2.8.1

[mmo]

I am trying to upgrade an application still using GWT 2.7.0 to at least 2.8.1 (and if possible higher, i.e. 2.9.0 or ideally 2.10.0).

After raising the GWT version from 2.7.0 to 2.8.1 the compilation of the UI maven module now always ends in an internal compiler failure:

ANY idea or hint anyone, how to analyze this? Or how to figure out what could be causing this and where to start searching???

 This line indicates that you have some version of JDT / ECJ on your classpath during GWT compilation that is incompatible with the one that GWT compiler uses. JDT is embedded in gwt-dev.jar so it is possible that some other dependency brings in a different version.
