InfoQ: State of Performance and Stability in Java 7 Update 1


Good to know that Java 7 Update 1 is there now, and it has been there for quite some time.


  • On October 18th, Oracle released Java 7 Update 1, bringing Java 7 much needed stability and fixing a performance optimization issue in which the HotSpot compiler could occasionally lead to incorrect results or could even SIGSEV crashes, as we previously reported
  • The same issue is fixed in JDK 6 with Update 29 where it occurred only when -XX:+AggressiveOpts or -XX:+OptimizeStringConcat were used, which is not recommended for production servers.
