We have run into crashes while using nrjavaserial, especially when we try to restart our app which is using serial port:

Hello,

I can confirm this behaviour. The runtime environment crashes during the connection on Win10/Java 11. I got an error, i.e. GetCommMOdemStatus failed!.

This issue is about a JVM crash with Java 8 on Linux (amd64/aarch32).

The library crashing the JVM with Java 11 on Windows is another known issue, see https://github.com/NeuronRobotics/nrjavaserial/issues/131.

both of these should be addressed in 3.19.0
