JVM green vs. native threads

Hi all,

I read somewhere that now Java supports native a well as green threads
that users can choose which model is used when the JVM interprets
their code. Is this the case with Jython, or does it depend on the
JVM?

Thanks,

Sarah

Green threads has been deprecated and removed from the Sun JRE a long
time ago.  Threads in Jython are (I believe) translated into Threads in
the JRE, which are in turn mapped to native threads of the underlying
operating system.

Correct, user level threads in Jython are mapped to/from standard Java threads on the JVM.
