Description:
============
Window pops up with the error message of  java.lang.OutOfMemoryError: PermGen space error.  Note PermGen stands for Permanent Generation and is memory space separate from the Heap Space.  It is for Classes and internal JVM objects.

Environment:
==========
Known to happen on Windows XP and possible other platforms.

Symptoms:
=========
Please attached resolution document.  When running jcosole, which is part of JDK 1.6, you will see that there is a missing XX:MaxPermSize setting in the VM Arguments.  The default size for PermGen space is 64 megabytes.

Cause:
=====
The virtual memory settings are incorrect to use Studio for the hardware configuration on this machine.  

Resolution:
=========
The TIBCO_HOME\\be\4.0\studio\eclipsestudio.ini controls the setting for PermGen in the -vmargs section.  Typical settings look like:
-vmargs
-Dacl.config.path=configuration/ACL.xml
-Xms1024m
-Xmx1024m
-XX:MaxPermSize=256m

If -XX:MaxPermSize=256m is instead on the line:
"C:/tibco_401/be/4.0/eclipse-platform/eclipse/plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.101.R34x_v20080731" or on the line immediately after remove it from there.

1). Try setting -XX:MaxPermSize=256m to 128m.  

2). If that does not work then lower -Xms to 512m.  This setting controls the start up size for Heap Size.  

3). If that fails then set -Xmx to 756M .

Studio gives a JVM Terminated with exit code -1 or an internal error occurred during: "Building workspace" with java.lang.OutOfMemoryError: PermGen space error.
