I've successfully gotten a "not too big, not too complex" Cocoa/Java
application working (three windows, a few sheets, lots of file reading, and
printing). I've not tried anything more challenging than that at the
moment, though.
In my experience, there are a couple of bugs that I've run into with the
bridge, but they're all VERY repeatable (beware of creating >15 NSTabStops
more than once!). I've also heard/read of other problems, though I've yet
to come across them myself. I've not had problems with things tanking at
random spots in my code, as you apparently have.
If you're planning on making a career out of Cocoa, I don't think anything
can save you from Obj-C at this point. For the foreseeable future, it's
going to be faster, more full featured, less buggy, etc. If you're just
doing this as time permits (like me), the Java bridge generally works well
enough to get most things done. Just file as many bugs as you can find, so
that there's hope for the future.

all!!!"). I just want to be able to work.
