Looks like nobody had an idea how to reproduce / address this issue? Matthias, do you have an hints on what might trigger this? Or even an idea what caused the infinite recursion (given you could in fact observe it in the debugger)?

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. If you have further information on the current state of the bug, please add it. 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. -- The automated Eclipse Genie.
