That would also be possible.  But what do you not like about the current 
method?
Doing it this way makes it possible for the Thread Dump functionality to 
work when
the JVM is being run standalone.  Without the Wrapper process 
controlling it.

The native library is also used for trapping system signals and giving 
WrapperListener
implementations a chance to handle them.   The native library is 
critical on Windows
systems to prevent the JVM from being shutdown if the user logs off.
