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.
