[ BUILD # : 4.0beta-1 ]
[ JDK VERSION : J2SE 1.5.0 ]

Built the "MyApp" sample program by pressing Shift-F11. Maxmimised the "output" window by double-clicking the title bar. Then minimised the window by double clicking the title window again. This produces the exception dialog:

javax.jmi.reflect.InvalidObjectException: Object with MOFID 18349D6B-F5BA-11D8-B9BB-4E826C7CAA77:0000000000000C1D no longer exists.
