Attempting to display the heirarchy for an interface in a set of interfaces that utilize generics results in a 100% reproducible internal error. I will attach the source files. Similar internal errors result when doing various refactoring operations on the interfaces. I've also reproduced this on Mac OS 10.4. As a particular example attempting to show the hierarchy for com.xxx.yyy.Validatable in the provides source yields an exception with the following stack trace is:
