Description Hannes Kegel CLA 2007-05-15 11:44:18 EDT 
Build ID:  I20070503-1400

When a class A implements an interface with method M, and M is only implemented in a superclass of A, the two methods are not connected with constraints.

Use Supertype Where Possible can produce results with compile errors in these cases. 

Steps to Reproduce:
0. Import sample project.
1. Use Supertype Where Possible on Target, select SuperTarget
2. Compile error: "OtherSubType must implement ..."

Additional Information:
The Rename-Refactoring handles this case correctly (in RippleMethodFinder2).

help is welcome!
Comment 3 Hannes Kegel CLA 2007-05-16 05:11:12 EDT 
What Infer Type currently does to handle these cases is a bit expensive. I am working on improving it. When I am done I will try to propose a patch.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
