Turns out the real issue was in the `tryLock` method, which just silently returned `null` when the file couldn't be locked. Also today I learned that `try-with-resources` will happily accept `null`, so this was never spotted. The end effect was that there was no concurrency control, all processes would access the file without coordination. I've added a process-based test and fixed the tryLock method so that it does the retry loop until it gets a non-null lock or the timer runs out. In fact, I could revert all the other changes, the tryLock turned out to be the only true issue. To me, DataInputStream/DataOutputStream seems more straightforward than the memory mapped buffer.
