Subject Re: Starting a Java application in the background.

You are mixing up the children and parents relations of the two.  A java
task is a child of the ant process.  Killing the ant process will kill 
its children as well.
With the java process still living after ant died the children died and
the parent still lives.

There is a way on linux to 'detach' a child from its parent. No idea if
Java supports that.

So; like Steve said; its quite hard to write :)
