Requesting approval to integrate hs23-b21 into jdk7u4-b20. A webrev is available at:
http://cr.openjdk.java.net/~jcoomes/7u4/hs23-b21-jdk7u4-b20.webrev/ SQE is evaluating the fixes; the integration will proceed only after SQE has approved. The fixes in the proposed integration are below. The fix for 7159766 simply disables tiered compilation by default. It has undergone nightly testing, but is not in a jdk8 repository because we plan to resolve the performance regressions while keeping tiered compilation enabled in jdk8. However, that is too risky for jdk7u4. 7158135: new hotspot build - hs23-b21 7159766: Tiered compilation causes performance regressions -John
