java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)

A DESCRIPTION OF THE PROBLEM :
IllegalArgumentException - not thrown when ncl is not a
registered.
Instead ArrayIndexOutOfBoundsException thrown.

Similar to 4400732 (closed, fixed) which only removes a
listener that is not registerd.

This testcase first adds a listener and then removes one
that is not registered.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. run class Test below


EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected:
IllegalArgumentException

Actual:
ArrayIndexOutOfBoundsException

ERROR MESSAGES/STACK TRACES THAT OCCUR :

Exception thrown = java.lang.ArrayIndexOutOfBoundsException
Test Fail
java.lang.ArrayIndexOutOfBoundsException
at java.util.prefs.AbstractPreferences.removeNodeChangeListener
(AbstractPreferences.java:1083)
at Test.main(Test.java:16)


REPRODUCIBILITY :
This bug can be reproduced always.
