> 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 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
