Equinox is R5 implementation and new major version always introduce incompatibilities so this is not surprising at all. It might be worth the effort to port to R5.

Is this still true? I know that jtulach(one of the netbeans guys) has his own equinox(like?) framework called Netbinox for usage in netbeans so you might want to get in contact with him for details. I haven't followed Netbeans in years but if you point to concrete problem I'll take a look.
