Groovy 2.1.2 appears to fix a critical issue in generics

[rvowles]

We are getting this error in the Eclipse Maven plugin (using 2.1.1). We were using 2.1.1 and getting the same error using the IDEA compiler, but on swapping to 2.1.2 this problem has gone away and all our tests using Mockito now work with @CompileStatic tagged. When attempting to build under Eclipse Maven with the additional 2.1.1 dependency, this problem still occurs.

Any chance of a 2.1.2?

Do you know what code triggers this exception? Or, even better, do you know which groovy bug this orresponds to? We can get a 2.1.2 out there, but that may take a few days. But adding a patch for this particular bug would be much faster.

ps- our issues tracker is http://jira.codehaus.org/browse/GRECLIPSE You will get a faster response if you post there.

Thanks - I have a developer attempting to isolate the issue into a separate artifact, which is proving more difficult than expected.
