Cause:
============
The exception is thrown from package java.util.zip when reading the .jar file. It indicates there is an issue with the Java Runtime Environment (JRE). To verify this, try any jar file. Probably the JRE is corrupted if the same UnsatisfiedLinkError appears.  


Resolution:
============
Either of the following options should work:

1). Run the TIBCO TRA installer, select custom install, and re-install the Java Runtime Environment.

2). Replace the current JRE with a new one. (SOL1-6ZJ8BH)
