JRE failure when running FEST tests

[jim618]

When running FEST tests I see the stack trace:

A fatal error has been detected by the Java Runtime Environment:

 The crash happened outside the Java Virtual Machine in native code.
 See problematic frame for where to report the bug.

Process finished with exit code 134

Assigned to Gary as it is most likely caused by something in the 'Trezor/ KeepKey plugging in and out' code.

In the most recent run of the FEST tests I didn't see any instances of these, not the MBHD CrashReporter whilst tests were running so closing.
