question: Embedded scripting language on console

Hello all,

I looking for some information on existing embedded scripting language on console (ps2, gc).

My goal is to design some behavior with UML state diagram then generating the code for the
scripting language. I have found that Java or python are appropriate language (with rational rose , together soft etc...)
but after some research i have this result:

java is use in Vampire the masquarade base on embedded java language and JNI. But no information
on other game (PC or console).
Is java interpreter (jvm) can be support on console because the lack of ressource ?
(Nota: About vampire, a presentatoin of this script engine have been made in GDC99 by Robert Huebner of Nihilistic but the slide are now unavailable, is someone have it or can send a link, thanks)

python is use in many PC game , again i found only few console game base on python scripting
but i think some use it.

I want use a popular existing language in order to each new team member are quickly functionnal
so no proprietary language.

The lua language seem to be a good alternative for embeded scripting on console (light an easy)
but there is no support for UML stuff.

I already know some web site on glue code for scripting language (SWIG) but 
i think the major problem is beetween the virtual machine and the need of ressource and on this point
few information is available.

In last is multithreading in scripting language (like java) can be emulate on console
for a real-time game ?
Is there programmer that have already implement one of this language and can give feedback ?
Thank a lot

Sorry for my english
Best regards.
