HP-UX 11i Java JDK/JRE Version 5.0.30 Release Notes

Using linker option +noenvvar and +compat on HP Integrity and PA-64
systems
If your application links with libjvm and uses the JNI interface APIs to load the JVM
directly, do not use the linker options +noenvvar or +compat on HP Integrity or PA-64
systems.
Running Java with setuid or setgid on HP Integrity and PA systems
Java requires dynamic loading (SHLIB_PATH, LD_LIBRARY_PATH) which are disabled in
setuid or setgid executables. Therefore, Java cannot run with setuid or setgid.
Running Aries PA-RISC emulation on HP Integrity
A patch is needed if you are using the Aries emulator to execute PA-RISC Java applications
on Integrity systems running HP-UX 11.23 or 11.31. The patch corrects a defect that
causes Java math calculations to produce incorrect results. This defect is fixed by installing
the following patch or any patch that supersedes it:
HP-UX 11.23 PHSS_35528
HP-UX 11.31 PHSS_36311
Java WebStart
Java WebStart does not currently support the automatic downloading of JREs that may
be requested by a JNLP file. You will need to install any specific JRE versions required
by an application prior to running that application. To download the version you require,
go to Java™ Technology Software on HP-UX. After the new JRE is installed, you will must
add the new JRE to WebStart. For more information about WebStart, see the Oracle's
Website at: http://www.oracle.com/technetwork/java/javase/tech/

Using -XX:+UseTimedWait to correct kernel application hang on Itanium
An application hang which has been identified as a problem in the kernel, may occur
on rare occasions on Itanium systems. As a workaround, HP recommends using the option
-XX:+UseTimedWait. If the problem persists, enter a Bug report. However, it is advised,
that use of option -XX:+UseTimedWait has a performance impact, and customers are
recommended to check any update on the recommended patch list for Java on Itanium
systems. The recommended patch list will be updated as soon as a fix is released as a
Kernel Patch.
