Yes, I know.

On the other hand I have failed to understand that API (I don't know
Java and I've not spend too much time with it though) and when I look at
Subclipse, it's just HUGE. The whole SVK, which is a subversion client
on top of subversion libraries, is some 13kloc(perl), while Subclipse,
which should be roughly the same complexity, is some 50kloc(java) IIRC.

To me it seems that either Java is not actually a very expressive
language, or that the API is on the wrong level -- or most probably
both.

Java, being strongly typed and JITed is still quite a bit faster than
python. Psyco may make some difference, but they don't currently have a
working psyco on Shootout.

For sake of development speed, python and perl are the only reasonable
choices. I'd certainly need bindings for Gtk and Gnorba/Bonobo for Gnome
integration, binings for Qt and DCOP for KDE integration and ability to
run the code from vim (for vim integration, of course). Ablity to run
call both perl and python code directly is a big bonus (perl can call
python and can make python call back to perl, but I am not sure it will
work when python is top-level)
