documentation

"Runtime support and environment for Java. 

You shouldn't communicate with JavaVM directly, 

use Java class instead. JavaVM is layer between

the native interpret and the rest of the system.

JavaVM implements native java virtual machine 

methods called by interpret, hides java primitive 

types handling, and gives the ST world ways to 

control class loading and reflection"
