I do get issues quite often (for groovy-eclipse tooling) that expect traits, @PackageScope, @TupleConstructor and so on to be cross-compatible with Java code in the same project. I have experimented with improving the experience, with some success but also some circular dependency issues. https://github.com/groovy/groovy-eclipse/commit/9e1f1a753cecba8320da3fba757b7d64cfd091a5
