Title:
  After applying Java Updates, KeyMusician Keyboard application won't
  run

Status in java-common package in Ubuntu:
  New

Bug description:
  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:

  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.
