The code listed after the stack dump causes the following
exception to be thrown when run under JDK1.3beta for Win32. It works
properly under JDK1.2.2. If JTable creates the
TableColumnModel, it works under both versions.

Under Solaris 2.7, the exception is thrown if you click on either cell once.

java version "1.3beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3beta-O)
Java(TM) HotSpot Client VM (build 1.3beta-O, mixed mode)
