java.util.concurrent.TimeoutException: org.moe.natj.general.Pointer.finalize() timed out after 10 seconds

From time to timeI I get this crashlog from my libgdx/moe app.

> java.util.concurrent.TimeoutException: org.moe.natj.general.Pointer.finalize() timed out after 10 seconds
> java.lang.Daemons$Daemon.isRunning(Daemons.java:84)
> java.lang.Daemons$FinalizerDaemon.run(Daemons.java:186)
> java.lang.Thread.run(Thread.java:818)

Any suggestions what this can be?
