After I tried installing latest jdk 1.7.0_21 on my own PC to run some test.
It fails to read a jar with java arguments in a jsp and having IOException on the latest build of jdk.
However, if I switched back the plugin/jdk to 1.7.0_17 then it will not having any problem in loading .jar.pack.gz.
Is the packEnabled function being removed in latest build ?
Argument in JSP file to load applet with pack.gz.*
<param name='java_arguments' value='-Djnlp.packEnabled=true'/>
Exception in console*
network: Disconnect connection to http://sample.com/applet.jar.pack.gz
