Thanks for posting the log. You need the debug symbols for your JVM installed.

  • If you’re using a JVM supplied with your distro see
  • If you’re using a JVM you’ve downloaded directly from e.g. OpenJDK, Azul or Oracle the debug symbols may or may not be included by default. If you let me know JDK vendor and version I can advise.
