Interestingly, the newest Java memory feature (Panama FFI/M) actually can catch you if threads race on a memory allocation. They have done a lot of rather complex and little appreciated work to make this work in a very efficient way.
The new api lets you allocate "memory segments", which are byte arrays/C style structs. Such segments can be passed to native code easily or just used directly, deallocated with or without GC, bounds errors are blocked, use-after-free bugs are blocked, and segments can also be confined to a thread so races are also blocked (all at runtime though).
Unfortunately it only becomes available as a finalized non-preview API in Java 22, which is the release after the next one. In Java 21 it's available but behind a flag.
