[pkg-eucalyptus-maintainers] Bug#685587: libgwt-dev-java: crashes on compiling a GWT hello world

[Alexandre Rossi]

Package: libgwt-dev-java
Version: 2.4.0-1
Severity: important

The patch to port GWT to the newer Eclipse JDT version seems buggy as
compiling a simple GWT application crashes the compiler.

I used the GWT 'Hello World' from :
    http://code.google.com/p/gwt-maven-helloworld/

If I use the precompiled GWT from upstream it works.
