webrev: http://cr.openjdk.java.net/~ccheung/jdk16/8247529/webrev.00/
This proposed change includes:
1) Avoid inserting InstanceKlass into the DumpTimeSharedClassTable after
dynamic CDS dumping has started.
This is done by adding a _dump_in_progress bool which will be set at the
beginning of dynamic CDS dumping. In
DumpTimeSharedClassTable::find_or_allocate_info_for, if the
_dump_in_progress is set, it will not create a new entry in the table.
2) Acquire the DumpTimeTable_lock before iterations on _dumptime_table
to ensure memory order correctness.
Testing: passed tier1 - 4 tests.
thanks,
Calvin
