Description Brock Janiczak CLA 2004-12-21 19:11:59 EST 
Version: 3.1.0
Build id: 200412210800

When opening up my workspace i got the following exception.  Removing all
breakpoints and restarting fixed the problem.  Sorry, no steps to reproduce.

java.lang.ArrayIndexOutOfBoundsException: 170

Comment 1 Darin Wright CLA 2004-12-22 08:35:06 EST 
Moving to JCORE, exception is in handle restoration code.
Comment 2 Jerome Lanneluc CLA 2005-01-04 07:11:51 EST 
It looks like the memento was bogus. Will add a protection against
ArrayIndexOutOfBoundsException.
Comment 3 Jerome Lanneluc CLA 2005-01-04 11:31:21 EST 
Protected all calls to MementoTokenizer#nextToken() with a hasMoreTokens() check.
Added regression test MementoTests#testInvalidMemento()
