Vector explicitly throws ArrayIndexOutOfBoundsException when a Vector
index if out of bounds. 1.0 APIs...

As far as I can work out the original poster seems to think the
exception occurs because he is using Swing from multiple threads. An
advocacy group is the right place to bash your head rather than bother
correcting bugs.

Perhaps there is a bug where removing focus from an almost empty editing
table whilst doing some update from a listener causes problems. But we
only have one line of code.

Sorry I got your point.

May be I posted it to the wrong group

Anyway After developing a proper example of the above problem I will
post the question to other Java Forums/Group

Bye for now
