code: @Override
      public boolean existsInStore(IEntityLock lock) throws LockingException {
          Class entityType = lock.getEntityType();
          String key = lock.getEntityKey();
          Integer lockType = lock.getLockType();
          Date expiration = lock.getExpirationTime();
          String owner = lock.getLockOwner();
          IEntityLock[] lockArray = getLockStore().find(entityType, key, lockType, expiration, owner);
  
          return (lockArray.length > 0);
      }
