[jbossts-issues] [JBoss JIRA] (JBTM-957) NullPointerException found in com.arjuna.ats.internal.jts.orbspecific.coordinator.ArjunaTransactionImple

[Mark Little (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/JBTM-957?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12648925#comment-12648925 ] 

Mark Little commented on JBTM-957:
----------------------------------

Just confirming a conversation Jonathan and I have had: in the C++ implementation, createTransactionHandle in OTS_Control also did a setControlHandle. The Java version of createTransactionHandle doesn't do that any longer and the ServerControl constructor was obviously overlooked when making the change. So an explicit call to setControlHandle should be in there.

> com.arjuna.ats.internal.jts.orbspecific.coordinator.ArjunaTransactionImple's doBeforeCompletion() method assumes that the "controlHandle" field is initialized to a non-null value.  However, com.arjuna.ats.internal.jts.orbspecific.interposition.ServerControl does not do said initialization despite the fact that the apparent contract published in com.arjuna.ats.internal.jts.orbspecific.ControlImple specifies that "The derived classes are responsible for setting everything up, including adding the control to the list of controls...".
