Description

Here is related code:

    Connection conn = null;
    boolean committed = false;
    try {
      conn = getConnection();
...
    } finally {
      if (!committed) conn.rollback();
      conn.close();
    }

If getConnection() throws exception, conn.rollback() would be called - leading to NPE.
