      Description

        Dacapo pmd benchmark (`java -jar dacapo-9.12-MR1.jar --size large --iterations 20 pmd`) regressed 5-20% on all platforms.

        This is caused by JDK-8313678, which fixed a symbol leak, but the leak was actually beneficial to performance in some cases as it allowed cheap temp symbol re-use instead of churning symbols with the associated cleanup and recreation cost.
