There's nothing unrecoverable about Error exceptions. If one thread hit a bug and threw StackOverflowError, it's not a reason to kill the entire application or even thread itself, just unwind stack, show some error and continue processing next task. The only tricky situation I'm aware of is OutOfMemoryError, because it can affect other threads. I'd prefer to restart the server. But again it's just because typical code allocated heap all the time. One can write code carefully without heap allocations and this code will work just fine with OOM errors thrown around.
