![]() ![]() SPARC T4 contains on-chip(native) cryptographic implementations. SPARC T4 specific crypto optimizations in the security area For a complete list of bugs fixed in this release, see. The new JAXP 1.4.6 version includes fixes for critical issues in the areas of conformance, performance, and regressions. For more detailed information about G1 see the G1 documentation page and command line options. Applications that require a large heap, have a big active data set, have bursty or non-uniform workloads or suffer from long Garbage Collection induced latencies should benefit from switching to G1. The G1 collector is targeted for applications that fully utilize the large amount of memory available in today's multiprocessor servers, while still keeping garbage collection latencies under control. ![]() Starting in Java SE 7u4 the Garbage First Collector is fully supported. New Supported Garbage Collector: Garbage First (G1) Starting from Java SE 7, the JVM no longer guarantees constant order of methods and JMX MBeanInfo no longer guarantees equality of MBeanInfo between two identical MBeans. In previous versions, the JVM used to return the methods in the declaration order and some user code may have relied on this behavior. To revert to the previous default behavior, use the option -XX:-UseParallelOldGC on the java command line.Īccording to specification, the JVM should not maintain any particular order of methods being returned by reflection. Parallel Old GC ( -XX:+UseParallelOldGC) is now enabled by default whenever -XX:+UseParallelGC is enabled.
