My application has a JTable with a Model that extends from
DefaultTableModel. If I run inside JBuilder 3 (which has jdk 1.2) works
fine. If I run it outside JBuilder with jdk 1.2.1 it also works fine,
but if I run it with jdk 1.2.2, it crashes with the following error:
Does anybody knows if there is a change in the new version?
Thanks
