Error when compiling sample GWT Gadget app

I am trying to get the GWT sample Gadgets app to run based on the example given here. When I compile the code I get the following exception:

[ERROR] Unexpected internal compiler error

I have the following major dependencies for my project:

  1. gwt-user v2.6.1
  2. gwt-gadgets v1.0.3

I am using java 1.7

Can someone please tell me what I am missing... been googling the whole day and found nothing useful

gwt-gadgets 1.0.3 was compiled a long time before GWT 2.6.1. It sounds like there might be some breaking changes in GWT which affect gwt-gadgets calls into gwt-user.

You should be able to get the source for gwt-gadgets and fix/compile it against a more recent version of gwt-user, or failing that you might have to use an older GWT more in line with the release date of gwt-gadgets 1.0.3 (May 2009!)
