What javascript min tool is jQuery using?

Question

I have a lot of javascript that must be min'd before it is passed to the end user. I am currently using JSMIN, but I would like to switch to something more powerful (e.g. replacing a local variable). I am currently looking at YUI min developed by yahoo and it made me think about the min tool that uses jquery. Does anyone know what it is and if it is publicly available? Also, any recommendations on other minimal tools that might be better than YUI min? If possible, I would like to use a Java solution, so I can just connect the library to what I have already created for the JSMIN solution.

thank
