6920346: G1: "must avoid base_memory and AliasIdxTop" Summary: Reviewed-by: The fix for 6877254 added a new field to StoreCMNode but the size_of, hash and cmp routines needed to be implemented to make cloning and hashing work correctly. This particular failure is caused by size_of reporting too small a size so the clone has uninitialized fields. The fix is simply to implement the needed routines in the obvious way. Tested with dacapo bloat test. |
