JVM crashed

Sometimes JVM is crashed after closing the device in Linux. In Windows it not appear. I use Ubuntu 16.04

I use cycle for catch problem, but jvm crashed periodically without open-close cycle

This might be due to an internal bug in the OpenJDK JVM but you are using the latest available version (u112) so I'm inclined to suspect a problem in the underlying libraries and JNA.

Could you pick through the additional error log /home/anama/Projects/JavaUsb/hs_err_pid5125.log to see if there is more detail that you could post here?

Any progress on this item? Similar behavior on Raspberry Pi (ARM) and Mac (iOS)

This could be related to a general requirement to upgrade hidapi so I'll reference it against #81 and ask anyone affected to try the new libraries currently on the develop branch.

Closing to avoid duplication.
