Class Loader Problem

Hello BIRT community,

I wanted to know about the js.jar file used in BIRT. It seems that there are the Rhino libraries. Now we have very strange situation with the class loader. The main application uses Rhino as library and when the BIRT module is started SecurityException is thrown because the classloader finds FunctionNode twice and then probably the SHA1-Digest code is used on the wrong class (Rhino jar) and fails.

Is this issue known?
Thanks for any hint and suggestion.

    If you already have js.jar in the classpath, try removing it from BIRT.

    Understood. Can you try 3.7? Remove the js.jar from the web-inf/lib of the viewer.
