This is different from the JVM stuff the OP mentioned...

Starting with Java 1.5, its JVM supports the concept of "shared memory", which has nothing to do with sharing data between related programs, such as parent/child.

What it does is that, when a JVM tries to load a module/class, Java will first check whether the same class/module has already been loaded by another JVM. If it is, instead of reload the class/module, the loaded one will be used/shared between JVM's.
