HP-UX 11i Java™ JDK/JRE Version 6.0.22 Release Notes

Equivalent Oracle release
This HP JDK 6.0.22 release includes the functionality, enhancements, and fixed defects
equivalent to Oracle releases up to and including 6u71, as well as certain HP
platform-specific fixed defects. The HP JDK 6.0.22 release passes all of the tests in
Oracle's Java Compatibility Kit test suite (JCK V6b). The experimental option
-XX:+UseG1GC is not part of the officially supported product, but is available for
experimentation. Other experimental JVM options in Oracle's JDK releases available
since 5.0u19 (for example, -XX:+DoEscapeAnalysis, -XX:+UseCompressedOops,
and similar options) are not supported in JDK/JRE 6.0.22.
HotSpot JVM
All -X options supported in earlier HotSpot JVMs are included in this version. Performance,
tool support, tool enhancements, and features are documented in the HP-UX Programmer's
Guide for Java 2 and the Java Troubleshooting Guide for HP-UX Systems on the HP
Support Center (HPSC) at http://www.hp.com/go/hpux-java-docs, and at the Oracle
web site: http://download.oracle.com/javase/6/docs/. For a list of -X options, see
the "Hotspot Technology Tools and Commands," section of the HP-UX Programmer's
Guide for Java 2.
The HotSpot JVM for HP-UX 11i for HP Integrity and HP 9000 PA-RISC systems is suitable
for both client and server workloads. For client-side workloads, -XX:+ClientApp will
invoke the JVM with configuration options that suit client-side applications.
The JDK 6.0.22 HotSpot 6.0.22 Edition supports the APIs core to the Java 2 platform,
among them Remote Method Invocation (RMI), nonblocking I/O APIs, the Collections
Framework, and IPv6. The Java 2 Platform version 6.0 API specification is available at
http://download.oracle.com/javase/6/docs/api/index.html.
The JDK 6 Adoption Guide will help users upgrading from JDK 5 to JDK 6. This guide
