JVM crash on RPi B+

[matoushybl]

Hi, I've been trying to use this library on my RaspberryPi B+ with Gradle and Maven, but in both cases the JVM crashed because of SIGSEGV. I have also tried using java 8 and 7 but with no success either. Can you please tell me which logs should I provide to help fixing this or is the problem somewhere in my configuration?

Here is the crash:

Have you started your application under root user?

The root permissions seem to solve it, but how come the lack of permission can make JVM crash?
