Javaws & Jnlp Fix In Debian(Buster)

What is Javaws? #

The javaws command launches Java Web Start, which is the reference implementation of the Java Network Launching Protocol (JNLP).

Java Web Start launches Java applications/applets hosted on a network.If a JNLP file is specified, javaws will launch the Java application/applet specified in the JNLP file.

Issue #
