Java Embedded Python
JEP embeds CPython in Java through JNI and is safe to use in a
heavily threaded environment.
Some benefits of embedding CPython in a JVM:
Using the native Python interpreter may be much faster than
alternatives.
Python is mature, well supported, and well documented.
Access to high quality Python modules, both native CPython
extensions and Python-based.
Compilers and assorted Python tools are as mature as the
language.
Python is an interpreted language, enabling scripting of
established Java code without requiring recompilation.
Both Java and Python are cross platform, enabling deployment
to different operating system.
