// The class demonstrates how to get an exclusive file lock that prevents other threads and processes / JVMs from
// obtaining a lock on the same file. To do this, you need to synchronize a block on a file and acquire FileLock. See
// comments below for more details. Run this class in multiple JVMs and see each thread of each JVM acquires a lock in
// an orderly fasion.
