Description

Hello , everyone

I deployed pluto portal and testsuite on weblogic 11g. When testing Portlet Event, for example click the Complex Payload Event Test or Simple Payload Event Test very frequently, accasionally the container will throw the following Exception:
Exception in thread "testsuite.286TestPortlet!-1115531942|0" java.lang.NullPointerException

The exception does not occur every time, but it's easy to come out. You can click the Complex Payload Event Test very quickly and can see the exceptions.

Does anybody know about the solution of this issue?
