Description Nicolas Bros CLA 2010-05-04 10:24:56 EDT 
- Import the 2 attached projects
- Restart Eclipse
- Do Project > Clean
- Delete QueryGetJUnit3TestCases.java, QueryGetJUnit3Tests.java and QueryGetMethodsToTest.java (all at once)

You get a StackOverflowError. Here is a snapshot taken with the debugger (to have the bottom of the stack):

Comment 1 Nicolas Bros CLA 2010-05-04 10:26:31 EDT 
Created attachment 166958 [details]
projects to import
Comment 2 Nicolas Bros CLA 2010-05-04 11:48:17 EDT 
Fixed in revision 2190.
This was due to FacetSets not being removed from the EPackage registry before unloading the resource, because the initial copy of the registry which is used to restore was not initialized correctly.
Comment 3 Hugo Bruneliere CLA 2010-10-01 13:35:33 EDT 
Bug fixed.
