[SOLVED] Tuxguitar hangs on loading screen

Hi there,

up to a few months ago, I was using tuxguitar from aur successfully. After some recent system updates (unfortunately I can't pin the update down exactly, as I wasn't using tuxguitar that often), it does not start any more. I only get a black window (loading screen), and nothing else follows. Nothing is printed at the prompt, and by attaching -verbose" to the java command in "/usr/share/tuxguitar/tuxguitar.sh", nothing suspicious shows up, and after hitting "Ctrl+C", it terminates (I think normally):

$ tuxguitar
...
[Loaded org.eclipse.swt.widgets.Group from file:/usr/share/tuxguitar/lib/swt.jar]
[Loaded org.eclipse.swt.widgets.Button from file:/usr/share/tuxguitar/lib/swt.jar]
[Loaded org.eclipse.swt.widgets.Combo from file:/usr/share/tuxguitar/lib/swt.jar]
^C[Loaded sun.misc.Signal$1 from /usr/lib/jvm/java-8-openjdk/jre/lib/rt.jar]

[Loaded java.lang.Shutdown$Lock from /usr/lib/jvm/java-8-openjdk/jre/lib/rt.jar]

The CPU load very high, memory consumption ok. The newest versions of arch linux & tuxguitar are installed, I'm running the awesome WM. Different java versions (java-6-jdk java-7-openjdk java-8-jdk) also did not change anything.

$ tuxguitar -i

I downgraded tuxguitar, and with version 1.3.1-1, I get following error in addition

$ tuxguitar

	at org.herac.tuxguitar.app.TGMainSingleton.main(TGMainSingleton.java:35)

The black box stays the same, but the CPU load is 0.

I'm running out of ideas what to test next, what would you suggest?

Thanks,

Re: [SOLVED] Tuxguitar hangs on loading screen

This works. Shame on me for not looking carefully enough in the forum.

Thanks a lot, stewie!
