The test case with bug 4957990 has revealed an interesting crash that we are trying to understand. The crash happens with -Xint, with the CMS collector, if we run with perm gen collection and old gen precleaning enabled. The crash goes away if either of these is disabled. Further investigation is in progress. This may or may not be related to long-standing bug 4756801. The comments section will be updated as investigation proceeds. Priority may get readjusted as we learn more about the problem.
