Description:
============
Sometimes TIBCO applications may crash because of event "gpf" on an AIX platform. This behavior can happen to all Java applications such as domainutility, AppManage, bwengine, etc. It may happen even after a fresh installation.


Environment:
============
AIX 5.3, 6.1
TIBCO Runtime Agent 5.6.x, 5.7.x


Symptoms:
============
The program may give errors similar to the following and exits:

Cause:
============
JIT (Just-in-time Compiler) is a feature available in IBM's JVM and sometimes it may cause Java program to work improperly.


Resolution:
==========
It is suggested to turn off JIT if the Java application works incorrectly. To turn off JIT, simply set environment variable JAVA_COMPILER=NONE.
