Description
PIT: jnlp double launches on UNIX platforms

Steps to reproduce:
- install jre1.6.0_10 build 20
- run javaws http://nicole1.sfbay.sun.com:8080/JavawsMustangIntegTest/hellojaws/BAT.jnlp
you will see double launch 
Before (latest promoted jre) - after splash screen it is launched almost immediately.
Now - after splash you can see "Downloading application" window, then 
"Launching application" window , then again "Downloading application" 
window and "Launching application" window and finally application launched.

Below is BAT.jnlp (hellojaws.jar is not signed, no vm-args, only one property - jnlp.TESTNAME):

EVALUATION actually double launches on windows too, but for some reason automation dosn't object. The only reason for secure args to not be passed by the native code on the command line is the native code didn't see the jnlp file due to launching with URL arg.
