Transaction statistics for read-only + last record may go wrong --------------------------------------------------------------- Key: JBTM-3218 URL: https://issues.jboss.org/browse/JBTM-3218 Project: JBoss Transaction Manager Issue Type: Bug Components: JTA Affects Versions: 5.10.0.Final Reporter: Ondrej Chaloupka Assignee: Ondrej Chaloupka Priority: Minor Fix For: 5.next As discussed at https://issues.jboss.org/browse/WFTC-78?focusedCommentId=13808486#comment... there was seen a wrong statistics being reported at a remote ejb calls for WFLY. The number of committed transactions went bigger than the number of all processed transactions. This happens when the transaction consists of {{XAResource}} which announces to be read only during {{prepare}} call and with the second resource which is {{LastResource}} (https://github.com/jbosstm/jboss-transaction-spi/blob/master/src/main/jav...). In such case the {{onePhaseCommit}} could be called during the {{BasicAction#prepare}} call (https://github.com/jbosstm/narayana/blob/5.10.0.Final/ArjunaCore/arjuna/c...). In such case the statistics of committed transactions are increased during the {{onePhaseCommit}} method call and then during the {{phase2Commit}} at {{BasicAction#End}} call (https://github.com/jbosstm/narayana/blob/5.10.0.Final/ArjunaCore/arjuna/c...).
