Bug report for ya Kappa:

... without version numbers in the LWJGL libs you're making it's a bit tricky to say exactly which one we've got here, but it's the currently deployed version of Droid Assault crashing. Apparently OS etc details are:
Version 10.5.8
Processor: 2.66 GHz Intel Core Duo
Memory: 4GB 1067 MHz DDR3
Graphics: NVIDIA GeForce 9400
LWJGL 2.9.0
This'll be running on the system JVM. Apparently crashes on Java 5 and 6 (64 bit).
Cas :)
This should hopefully be fixed in the nightly builds of LWJGL 2.9.1 (http://ci.newdawnsoftware.com/job/LWJGL-git-dist/lastSuccessfulBuild/artifact/dist/lwjgl-2.9.1.zip) now, unfortunately requires access to OS X 10.5 so can't test to confirm.
Please do test and report any further issues.
