STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
The NPE exception in com.sun.deploy.security.CPCallbackHandler.isAuthenticated occurs randomly (likely by class loading) so precise step-by-step process cannot be described

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The NPE exception in com.sun.deploy.security.CPCallbackHandler.isAuthenticated should not occur
