[jira] [Created] (KYLIN-3556) Interned string should not be used as lock object

Ted Yu created KYLIN-3556:
-----------------------------

             Summary: Interned string should not be used as lock object
                 Key: KYLIN-3556
                 URL: https://issues.apache.org/jira/browse/KYLIN-3556
             Project: Kylin
          Issue Type: Bug
            Reporter: Ted Yu


In JDBCResourceDAO :
{code}
            public void execute(Connection connection) throws SQLException {
                synchronized (resPath.intern()) {
{code}
Locking on an interned string can cause unexpected locking collisions with other part of code.
