FULL PRODUCT VERSION :
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)


FULL OPERATING SYSTEM VERSION :
SunOS titan 5.8 Generic_108528-18 sun4u sparc SUNW,Ultra-60

A DESCRIPTION OF THE PROBLEM :
Choice.select(int sel) seems to post an event to the event
queue which then calls select again. If items have been
removed from the Choice in the meantime, an
IllegalArgumentException occurs.

java.lang.IllegalArgumentException: illegal Choice item
position: 3

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.In event handler, select(3) on the choice
2.Then in the same handler, remove all but two items from
the choiuce
3.Observe the exception.

This is illustrated in the source code; just compile and run
on a Motif system.
