Fix Request This bug was found by the Parfait tool and should be fixed because it could cause crashes in product code. The risk is very low because the fix is trivial. Tested by running all HotSpot tests (see last comment). Reviewed by Vladimir Kozlov. http://cr.openjdk.java.net/~thartmann/8180511/webrev.00/
