There is a memory leak in the swing-component JTable.
JTable adds itself to a TableModel in the method

 public void setModel(TableModel newModel)

But it never removes itself from that model until setModel is
called again. Remember - the TableModel could itself be
referenced from other objects. After JTable is being removed
from its parent component, such a back-reference stops the
gc to collect it !!!!

So JTable has to de-register itself from its model in case it
is not shown anymore. I suggest it overrides

 public void removeNotify()

and calls removeTableModelListener() from there. That way
it is insured that all references to the JTable-object are
cleared - garbage collection can occur then.
