The -J option to the 'jar' command means "Run the jar utility with this
option". It doesn't mean "Create a jar whose application will run with
this option".
There is no manifest or other jar-embeddable attribute that can specify
such options for a plain ordinary jar-file. You have to use something
else, like JNLP deployment, a batch or script file, or a Mac OS X
app-bundle.
