@headius Could you please have a look at this issue?

This appear to be ok on Java 8 but failing on Java 17+, probably due to module changes preventing reflective access to things the tests need to access (FileDescriptor internals, for example). The tests should be modified to open up the necessary classes by passing --add-opens into the Maven surefire task.

Could be a nice PR, want to try it?

@headius Thank you for your suggestion. It's interesting to note that the error mentioned above is not limited to Java 11 but also occurs with Java 8.

I have still been unable to reproduce this. Perhaps you could put together a container image that reproduces it and I can try running that locally?

All tests pass for me on Fedora Linux on x86_64.

Sorry for the late response. Sure I can create a container image and share with you the link to pull that image.

Thanks.
