SIGSEV upon program finish

[zyklone92]

First of all, many thanks for this project - it has saved me a lot of trouble and work for a private project of mine.
I am using a WS2812b LED-Strip on a RPi 3 via gpiopin 21, pwm-channel 0 and can use it without a problem. When the program finishes however (or I call System.exit()), I get a sigsev error and I strongly believe this is due to the corresponding channel not being closed properly, because nothing else could cause it. I even tried executing a program, where I just instantiate a new strip and send something and I still get the error.
Honestly, this is not super important, since everything works fine upon execution, but I thought I might post this here and see, if others get the same error, or if this behaviour is even expected.
Thanks again for this great contribution.

Sorry for the lack of a response, I was in the process of moving to a new home when this was written and forgot to come back to it.

I will review the code a bit to see if anything jumps out at me. Do you have a simple code example that causes the problem?

Greetings, install this library with some problems in my raspberry pi, for example I had to use:
./gradlew assemble -x signArchives
...

:processResources UP-TO-DATE
:classes UP-TO-DATE
:jar UP-TO-DATE
:javadoc UP-TO-DATE
:javadocJar UP-TO-DATE
:sourceJar UP-TO-DATE
:assemble

BUILD SUCCESSFUL in 22s

without the above, it generated an error:

:signArchives FAILED

FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':signArchives'.

Cannot perform signing task ':signArchives' because it has no configured signatory

• Try:
  Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

However someone could provide me with a simple example of how to use it in java.
thank you.
