class X extends Super<A<X>> { } ------------------- Moved mouse cursor onto the run button, got an error dialog asking to exit workbench. !ENTRY org.eclipse.core.jobs 4 2 2007-05-14 15:25:31.411

Kent - can you look at it pls ?
Actually, hovering onto the DEBUG button is required (not RUN).
Kent - to reproduce, pls get 'Crap' project v_001, and open X.java from default package. There must be sthg extra required to reproduce from my original testcase (likely some existing type).
Other case (maybe same): package p; import static p.Super.*; class Top<T> {} class Super<T> extends Top<T>{ } public class X extends Super<java.util.List<X>> { }
I think the secondary type cache is attaching Super to the package p even tho the file X.java is defined in the default package. We should never find Super in the first place to cause the stack overflow.
Created attachment 76207 [details] Proposed patch
Released for 3.4M1 in HEAD stream.
Verified for 3.4 M2 using build I20070917-0010.
