      Name: gm110360 Date: 06/20/2002


      FULL PRODUCT VERSION :
      java version "1.4.0"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
      Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

      Windows NT 4.0 (SP 5)

      ADDITIONAL OPERATING SYSTEMS :
      generic


      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 :
      ---------------output------------------------------
      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)

      This bug can be reproduced always.
