The problem has occurred when we migrated our LSMS Java GUI from Java 1.3
to 1.4.2.
Symptom: The GUI display is greying out after different time periods. Gui
could be functional from 5 to 30 minutes.

Problem area:
We have a table derived from AbstractTableModel. The GUI displays messages
in a tabular format. The messages (events) arrive and are displayed in a
table.
We call
fireTableRowsInserted(startRow, endRow);
and this call is not returning. There is a deadlock in the Swing library
see attached stack dump.
