Reproduced with HEAD. javac 1.5.0_10 is also failing. javac 1.6 and 1.7b06 seem to end up in an infinite loop.
Added disabled regression test org.eclipse.jdt.core.tests.compiler.regression.GenericTypeTest._test1102()
Removed the regression test.
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. -- The automated Eclipse Genie.
