This is the developer.
This bug is weird, I use Arch in all my machines and never encountered it, nor was the issue reported from any other distro or operating system.
Basically, there is a pool of vector objects to avoid memory allocation. Each frame we need to compute the RA/DEC position of hte mouse pointer. For that, a couple of vectors are requested (one contains the input screen x and y coordinates, the other is for the output RA/DEC/Distance information). As it turns out, the output vector returned by the pool is null, which is VERY strange.

Can you outline what more or less in what situation the crash occurs? Is it completely random? What is the camera mode? I created a new issue in github for this here:
Thanks for reporting!

The app. hangs up (always) after a while (it's random, sometime it takes longer, sometime right), but obviously with the very same "Exception in thread "LWJGL Application" java.lang.NullPointerException" failure:

I'm running:
Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz (Intel Skylake)
GeForce GTX 750


jre8-openjdk 8.u102-1

Is this happening to anyone else, whether I should report a bug to the developers?
