Examples of java.nio.channels.FileLock.release()

java.nio.channels.FileLock.release()
Releases this particular lock on the file. If the lock is invalid then this method has no effect. Once released the lock becomes invalid. @throws ClosedChannelException if the channel is already closed when an attempt to release the lock is made. @throws IOException some other IO exception occurred.
