Known Issues

Known Issues Pertaining to HP-UX JDK

If you are using releases of HP-UX JDK 5.0.04, HP-UX JDK 5.0.05, and HP-UX JDK 5.0.06, you may experience an out-of-memory error. Oracle recommends upgrading to the latest JDK version. See

Increase MaxPermSize

You may need to increase the MaxPermSize parameter based on application requirements. For example: For the WebLogic Portal Groupspace sample, you may need to increase the MaxPermSize from 128MB to 256MB.

Serial Version UID Mismatch

A serial version UID mismatch is encountered when using WebLogic Server with HP-UX Java 5 (JDK and higher).

Workaround: To be compatible with the serialization of previously compiled applications, modify the <BEA_HOME>/Weblogic91/common/bin/ file to include the following command:

JAVA_OPTIONS="$JAVA_OPTIONS -Dcom.sun.xml.namespace.QName.useCompatibleSerialVersionUID=1.0"

Alternatively, you can use the command line option:

export JAVA_OPTIONS="$JAVA_OPTIONS -Dcom.sun.xml.namespace.QName.useCompatibleSerialVersionUID=1.0"

Note: If you intend to deploy new applications with previously compiled applications, they must be recompiled as necessary to have the same Serial Version UID.
