Hi,
I've recently upgraded my PC from Ubuntu 20.04 to 22.04 and I'm now facing a JVM crash on a program using jnr-fuse and javafx. A similar crash can be easily reproduced with a Hello World javafx code and a call to to the MemoryFS mount method. The same program runs properly on Ubuntu 20.04. I have no idea whether the problem comes from the jnr-fuse, javafx ou even jnr-ffi layers. Have you ever heard of such issues?
Thanks
Eric
