The method RMIConnectorServer.setMBeanServerForwarder(MBeanServerForwarder mbsf)
throws NullPointerException instead of IllegalArgumentException
if the specified mbsf is null.

The API specification of the method JMXConnectorServerMBean.setMBeanServerForwarder reads:
  "IllegalArgumentException - if the call to mbsf.setMBeanServer fails with
   IllegalArgumentException. This includes the case where mbsf is null."

The following test fails running on JDK 1.5.0-beta-b25.
See below the test source and the execution log:
