To continue confusing the issue, there is the SWT which could
constitute a third class of windowing. SWT is implemented as , I
think, native components compiled for the OS, then wrapped with Java
using JNI. I suppose this could constitute a third "weightedness" but
it is available not only for Mac, but for almost all Java platforms.
It is also possible that what your colleagues mean is that Sun was
not responsible for writing the code for the Apple GUI stuff. That
was all Apple's doing. This is different from other Java platforms
like Windows or Solaris.
Cocoa* is in there somewhere too, but I do not do any GUI
programming on the Mac so I don't have the slightest clue how it fits
into the Mac/Java integration.
*it is entirely possible that when I say Cocoa I really mean Carbon.
