6982537: Crash in Node*step_through_mergemem Reviewed-by: Code which was examining the type of memory was attempting to introspect on the klass of TypeOopPtr but wasn't checking for NULL which led to crashes when it looked at a primitive array type. The fix is to check for NULL. I also updated similar code in escape.cpp and corrected variable names to match the types. Tested with failing test from bug report. |
