I've also had this in 3.6 RC3, with Sun's JDK 1.4.2_04 on Mandrake
Linux 9.2 (using the Metal L&F).

It doesn't do it under normal circumstances.  However, if I click the
"down" button to open the list, drag the mouse down the list while
keeping the left mouse button held, then click the right mouse button
while over one of the list entries (which I did accidentally the first
time) I get the same exception as listed below every time.

This code was completely rewritten for 4.0, and I cannot reproduce the problem now, so 
closing.
