Notable Bug Fixes in JDK 6u33

This list includes some of the notable bug fixes in JDK 6u33.

Area: hotspot/runtime_arguments
Synopsis: Improve VM configuration file loading.

JDK 6u33 contains changes to the default implicit loading of the .hotspot_compiler and .hotspotrc file. For existing deployments which rely on .hotspot_compiler (e.g. to exclude a method from hotspot compilation), an unsupported behavioral option has been provided to simulate the old loading behavior.

Command line options to support old behavior:

-XX:Flags=.hotspotrc
will revert to old behavior for .hotspotrc.

-XX:CompileCommandFile=.hotspot_compiler
for the .hotspot_compiler file.

Note: The following bugs are fixed on a build that was made available after the GA of JDK 6u33. If you experience the following issues, check your installed JDK 6u33 build number. If it is not b04(or b05 in Windows), get the latest JDK 6 update version from OTN.
