guava

Indeed. I recommend using tsan for java. https://wiki.openjdk.java.net/display/tsan/Main But the types of races I struggle with in java I suspect are similarly hard in Rust. Here's two pieces of concurrent code I struggled with: https://github.com/google/guava/blob/master/guava/src/com/go... https://github.com/google/guava/blob/master/guava/src/com/go... I'm not sure reasoning about the correctness of those would be easier in Rust, but if there are any rust experts reading this I'd love your perspective.

> But since you own the code, you own 100% of the source in your GUI application, why would you need indirection? So what is your proposed non-indirection way? I'm assuming you meant the traditional listener/observable way of registering event producers and event listeners together, in which case this FAQ explains pretty well their downsides compared to an event bus: https://github.com/google/guava/wiki/EventBusExplained#faq

I haven’t written Java in my day-to-day for quite some time now, but the first thing that came to mind for a good open source Java codebase is Guava by Google: https://github.com/google/guava It’s a collection of core libraries for Java that I believe should have a lot of useful patterns/concepts to learn from. I also highly recommend Effective Java by Joshua Bloch (https://www.amazon.com/Effective-Java-Joshua-Bloch/dp/013468...). An incredible text for any kind of programmer, and even better if you’re specifically interested in Java. Good luck!
