java version "1.7.0_09"
  Java(TM) SE Runtime Environment (build 1.7.0_09-b05)
  Java HotSpot(TM) 64-Bit Server VM (build 23.5-b02, mixed mode)

Does this problem occur on J2SE 6ux or 7ux? Yes / No (pick one)
  7u9 only

Operating System Configuration Information (be specific):
  MacOSX 10.7.5

Hardware Configuration Information (be specific):
  Macbook Pro 17" (late 2011)
  Core i7 2nd Gen
  8GB DDR3
  128 SSD

Bug Description:

Here is the java element from the JNLP file.
<java
    version="1.6.0+"
    initial-heap-size="128m"
    max-heap-size="768m"
    java-vm-args="-XX:PermSize=144m -XX:MaxPermSize=144m"/>

This works correctly on Windows and on MAC using 7U7. However, in & update 9 on a MAC, it dies a horrible death...
* Opening our jnlp from browser link
* Java icon shows in the Dock
* Jar files are verified
* Application never starts

The problem seems to be in one of the vm parameters. We noticed was that the -XX:PermSize is not (or no longer) supported, however, it does apparently still work on Windows.
(VM parameter list: http://www.oracle.com/technetwork/java/javase/tech/vmoptions-jsp-1401)

In any event, this is a difference between update 7 and update 9 on the MAC, and something different on a MAC than on Windows.

Remove the -XX:PermSize option, and the problem with go away as well. However, not find another way to adjust this setting.
