             Summary: Statement.cancel() is not invoked until the statement is completed
                 Key: WFLY-6662
                 URL: https://issues.jboss.org/browse/WFLY-6662
             Project: WildFly
          Issue Type: Bug
          Components: JCA
    Affects Versions: 9.0.2.Final
            Reporter: lorenzo benvenuti
            Assignee: Jesper Pedersen


Hi,

in our application we are using the {{Statement.cancel()}} method to stop long-running queries; in Wildfly 9.0.2 this is not working because the {{cancel()}} method is synchronized using a lock which is not released until the query is executed. In {{WrappedStatement}}:

{code:java}
public void More ...cancel() throws SQLException
    {
      if (doLocking)
          lock();
       try
       {
        /* ... */
{code}

It seems this behaviour has changed from version 1.2.5.Final of ironjacamar-jdbc; in version 1.2.4.Final {{WrappedStatement.cancel}} doesn't try to obtain the lock. 
Probably I'm missing something, but to me it's strange that in order to cancel a statement you have to wait for its completion.

Thank you,

lorenzo
