JRE crash in Java serial app with JSSC in W10 enviroment

Question

I'm new to Java and when trying to run the following code with jssc-2.8.0 library, at the "serialPort.openPort()" method the IntelliJ IDE crashes and reports:

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

EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x000000007110b5db, pid=11596, tid=5204

No core dump will be written. Minidumps are not enabled by default on client versions of Windows

Source code follows:
