KVMViewer_3.30a-1.jnlp

When using javaws (icedtea-netx-1.8-0ubuntu8, on Xubuntu 19.10) to run a jnlp
file generated by a Intel MFSys25 V1 (latest eol firmware), It fails due to
'Could not read or parse the JNLP File'.

I believe due to the following line at the end of the .jnlp file
<?-- JViewerVersion 3.30a -->
(Specifically deleting that line allows it to work.  This works out of the box
in Oracle's Java.

JNLP file is attacked with some information masked/removed.
