Troy in a previous post identified what is going on.  The kernel can
recognize a .class file as a Java byte code file.  Upon recognition, it
calls out to the Java VM that is part of the installed JDK and runs the
file.  What is does is rather than typing the following:

java FooA :where FooA is a .class file

you can type just

FooA

like any other native executable and the kernel will throw the file at the
VM for processing.  This only works if a VM is installed.

All that is Microsoft does not glitter,           
Not all those who wander are lost;                 
The old AT&T Unix that is strong does not wither, 
Deep roots are not reached by frost.              

From the ashes of Spec1170 a fire shall be woken,
A light from the shadows shall spring;            
Renewed shall be the Unix OS that was broken,     
Linux shall be king.
