Need help navigating the Java ecosystem (coming from C++)
Martin Thompson is one of the leaders in that space: his blog is a really great place to start. His Agrona library is a bunch of high-performance data structures, which you can use directly, but which can also serve as examples of writing such code.

WritableImage and real-time ray-tracing. I need help!
ByteBuffer methods have quite a bit of overhead. You could further try to (1) writing to a byte[] first and then using the put(byte[]) method, or (2) use sun.misc.Unsafe::putByte (maybe try with Agrona's DirectBuffer and copy the necessary lines if need be).

Java: Automating data setup in unit tests
Properly handling seeds and having reproducible objects was one of the main goals, so it should work as you'd expect. I'd suggest giving it a try and if you run into any issues, just post it on Github discussions.
