Libgdx crashing?

Newbie & Debugging Questions
#1

I’m working with libgdx and I’m getting an error message that looks just like this:

#
# A fatal error has been detected by the Java Runtime Environment:

AL lib: alc_cleanup: 1 device not closed

It happens after 25 seconds almost every time. I’m rather confident that it’s not an error on my side, but I’d like to know what’s going on.

Found a reference to alc_cleanup here…
And an error report (almost the same error) here…
Hope those help, I know they aren’t that relevant.

#3

Look at the log file referenced in the error message. Describe what you are doing, what platform etc.

I’m working on a top down tile based mining game, based off of the game Lego Rock Raiders. I’m only running it on PC. Here’s a pastebin for the error file. http://pastebin.java-gaming.org/7da697f8c54

I once had a similar problem and found the solution in this topic.
I didn’t post the error message in there, but it was an EXCEPTION_ACCESS_VIOLATION as well.

I had this kind of error before and posted it here and libgdx forum (and got ignored). I found the solution by myself, almost same with dermetfan’s.

Problematic frame is (likely) to be caused by disposable object, like Stage and its SB. I always disposed my stage on hide() before, because I want new stage for each screen. Then I moved the stage instance to Game class and let every screen to use it together by clearing it on hide(). With this I can safely dispose the stage on Gdx.app.exit(). Hope helping.
