This belongs to sunappserv module
This was a regression I noticed when I upgraded the plugin to use the sun dd api. It was caused by a change in the environment under which the tables using this model were being invoked, that was causing model.getRowCount() to be called before the table was even displayed (or initialized.) I do not know what the environmental change was - could be IDE change, swing init change in JDK 1.5, or sun dd api (I doubt this one), but regardless, the bug is a trivial fix and I did not notice any other bad behavior.
