Description:

RMI exception when launching the workpoint designer: com.workpoint.client.ClientContext - Attempt to verify authentication requirements from server failed.
java.rmi.RemoteException: NamingException caught attempting to locate the 'ServerConfigPvt_EJB' object.

Solution:

There was a behavior change in ClassLoader.loadClass() handling byte array. As discussed in:

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6434149

Adding this VM argument to client JVM preserves the backward compatible behavior of loadClass() and provides a workaround without patching JDK or WebLogic server:

-Dsun.lang.ClassLoader.allowArraySyntax=true
 

Add this java parameter to init.bat & designer starts up well.
