    Description

      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:

      public void cancel() throws SQLException
          {
            if (doLocking)
                lock();
             try
             {
              /* ... */
      

      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
