code: @Override
      public IEntityLock[] find(
              Class entityType, String entityKey, Integer lockType, Date expiration, String lockOwner)
              throws LockingException {
          return select(entityType, entityKey, lockType, expiration, lockOwner);
      }
docs: Retrieve IEntityLocks from the underlying store. Any or all of the parameters may be null.
  
  @param entityType Class
  @param entityKey String
  @param lockType Integer - so we can accept a null value.
  @param expiration Date
  @param lockOwner String
  @exception LockingException - wraps an Exception specific to the store.
