The version of about.jnlp in the jar should be identical to the copy 
installed at $(datadir)/icedtea-web/.

You might also want to refer to a recent thread [1] where various issues 
in javaws -about are pointed out, including the fact that about.jar is 
completely unused right now. The about.jnlp file indicates that the 
canonical copies of about.jnlp and about.jar are stored on the icedtea 
servers [2]; javaws uses _those_ files rather than the on-disk copies.

Jiri has indicated interest in fixing these issues. This patch is more 
of a quick hack just to keep the existing system (even though it's far 
from perfect) working.

Cheers,
Omair
