If I use jdk5 as project jdk, I can create GUIs (including user-defined component classes) as expected.
But if I change my project jdk to java6 i get an "unsupported class version" for all my user-defined components (red boxes are shown instead). 'Rebuild' does not help. Is this a bug or a feature? Is it possible to use java6 together with the current gui designer?
