How can I have a JTable update (in response to a TableModelEvent) and
prevent the data model from changing during the update?

I am getting ArrayIndexOutOfBounds exception during update and I believe
this is because the application is deleting rows during the update.  I have
used a lock to mutually exclude the application from changing the data model
and the JTable from reading the data; the latter locks the getRowCount(),
getColCount(), and getValueAt() methods.  The problem, I believe, is that a
row gets deleted between the time getRowCount() is called and all the
getValueAt()s have been made; the index in error is always one more than the
# of rows.

Is there a way I can have the JTable do the update atomically? That is, make
all it's calls with as a single transaction?

I can't use a more granular TableModelEvent, to specify the rows to update
because the application does not know where in the table the information
will appear.  Also, it is not the last row that is being deleted.

Thanks in advance for your help.
