Bump -- the problem still happens in GWT 2.5 RC2.

Here is the relevant output from the gwtc target in ant with -logLevel set to ALL.  I am using SmartGWT 3.0 (the current latest release); the error below suggests an incompatibility between the GWT 2.5 RC1 compiler and SmartGWT 3.0 (everything compiles fine with GWT 2.4).  Please let me know how I can be of further assistance.

I have the same problem after switching to gwt 2.5.0 from 2.4.0. Do you have any solution?

There was a similar question today on StackOverflow: http://stackoverflow.com/q/13641849/116472

The problem was a method with the same name as the class, apparently GWT confused it with a constructor.

I've written up an issue: https://code.google.com/p/google-web-toolkit/issues/detail?id=7824.  I tried to use Wiki syntax without success.  :)

Thanks,
