That is odd, since it seems pretty certain from the source code that it 
should.  What Java version are you using?
Nevertheless, you are telling the JTable that it should use your custom 
TableCellRenderer for rendering a cell in a column whose column class 
is *null*.  So I presume that it is not using your renderer.

You need to make sure that getColumnClass() for your TableModel returns 
the appropriate class, and then pass that class to setDefaultRenderer() 
as the first argument.  Alternatively, you could leave getColumnClass() 
as is and pass Object.class to setDefaultRenderer().
