    Description

      FULL PRODUCT VERSION :
      java version "1.7.0_01"
      Java(TM) SE Runtime Environment (build 1.7.0_01-b08)
      Java HotSpot(TM) 64-Bit Server VM (build 21.1-b02, mixed mode)

      (but this problem also exists in 1.5, 1.6, etc)

      ADDITIONAL OS VERSION INFORMATION :
      Linux beast 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux


      A DESCRIPTION OF THE PROBLEM :
      BreakIterator has problems with some supplementary character sequences. When iterating text that contains these characters, it throws an internal ArrayIndexOutOfBoundsException in RuleBasedBreakIterator.lookupState

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Run the included test program

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      it should not throw an exception, instead next() should return next text boundary or BreakIterator.DONE
      ACTUAL -
      Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 268
      at java.text.RuleBasedBreakIterator.lookupState(RuleBasedBreakIterator.java:1036)
      at java.text.RuleBasedBreakIterator.handleNext(RuleBasedBreakIterator.java:931)
      at java.text.RuleBasedBreakIterator.next(RuleBasedBreakIterator.java:621)
      at test.main(test.java:8)


      REPRODUCIBILITY :
      This bug can be reproduced always.
