Description

For Java7+, try-with-resources makes using locks safer. Curator should have a utility for this. Something like:

public class SafeLock implements AutoCloseable {
  private final InterProcessLock lock;
  private final boolean acquired;
  public SafeLock(InterProcessLock lock, long timeout, TimeUnit unit) {
        this.lock = lock;
        acquired = lock.acquire(timeout, unit);
  }

  public void close() throws Exception {
      if ( acquired ) {
           lock.release();
      }
   }
}
