I'm getting this exception fairly often when working with UML designer.

Comment 2 Thuy.d Nguyen 2007-11-02 00:41:26 UTC

This issue still exists in UML NB 6.0 and occurs on all platforms, not just linux or solaris.

Comment 3 Thuy.d Nguyen 2007-11-02 17:24:55 UTC

The same "Satisfiers" node was mistakenly removed multiple times if the node has more than one child nodes, which causes
the ArrayIndexOutOfBoundsException.  Fixed the code to assure the node being removed only once.

Comment 4 Joanne Lau 2008-01-24 21:53:41 UTC

Fix verified in NB 6.1 M1 build (200801222102)
