When we fixed the jmx bug 6696028, we expected to receive "RemoteException" as thrown by the current existing JDK6 (for example 1.6.0_10), but we got NullPointerException from the 6u12.

This possibly impacts other existing applications, so important to run JCK to verify the compability.

Here is the test:
/*
 * @test IllegalIIOPURLTest.java 1.1 08/11/06
 * @bug 6696028
 * @summary JMXServiceURL like service:jmx:rmi:///jndi/iiop:// should be
 * rejected by the RMI conn provider.
 * @author Shanliang JIANG
 * @run clean IllegalIIOPURLTest
 * @run build IllegalIIOPURLTest
 * @run main IllegalIIOPURLTest
