Statement.cancel() is not invoked until the statement is completed ------------------------------------------------------------------ Key: JBJCA-1321 URL: https://issues.jboss.org/browse/JBJCA-1321 Project: IronJacamar Issue Type: Bug Components: JDBC Affects Versions: WildFly/IronJacamar 1.3.4.Final, 1.2.7.Final Reporter: lorenzo benvenuti Assignee: Lin Gao Priority: Critical Fix For: WildFly/IronJacamar 1.3.5.Final, 1.2.8.Final 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
