Public bug reported:
After applying the latest Java updates (to open Java), the Keymusician
Keyboard application no longer runs.
When I run the JAR file manually in a terminal, I get the following
error information:
aere@aere-VGN-SZ430N:~$ java -jar KMK.jar -DebugLevel=2373

However, when I run the same JAR-file using Java Web Start (iced-tea),
it runs okay, using the same configuration.
When running it via Java Web Start, it appears the earlier problem I
reported, regarding the lack of slider-handles using the GTK+ look-and-
feel, has been fixed.
I am using Lubuntu 18.04.1 LTS.
On that system, default-jre depends on openjdk-11-jre, version
10.0.2+13-1ubuntu0.18.04.1
When I accessed the installed application (installed by gdebi), I
expected to run as it had been doing before.
Instead, it crashed early in the initialization process.
I tried running it manually in a terminal session, and got the error
reported above.
I tried running it via JNLP (Java Web Start, using icedtea), and it ran
okay.
Since it is now distributed as a Debian package, I need the installed
version to continue to work.
I can attach (if you request), the Debian package for installing it, the
JAR-file, and/or the JNLP file for launching it via Java Web Start.
Please let me know what you need.
