Description Eric Wasserman CLA 2005-07-01 20:56:18 EDT 
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:

Comment 1 Eric Wasserman CLA 2005-07-01 20:58:44 EDT 
Created attachment 24284 [details]
source that reproduces the error

The attached .zip contains a project that when imported can be used to
reproduce the bug. Open an editor on com.xxx.yyy.Validatable, select the class
name and "Open Type Hierarchy" (F4). Results in an internal error.
