[jboss-jira] [JBoss JIRA] (WFLY-10258) Prevent enlisting additional resources on EJB caller side in case of server side @RequiresNew

[Tom Jenkinson (Jira)]

    [ https://issues.jboss.org/browse/WFLY-10258?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13662143#comment-13662143 ] 

Tom Jenkinson commented on WFLY-10258:
--------------------------------------

I was thinking of doing the ordering each time that we commit the TX.

Something like:

tx.begin()
xar1.enlist(EJBRXAR to server 1)
_xars.add(xar1);
xar2.enlist(EJBRXAR to server 2)
_xars.add(xar2)
tx.commit()
xar1.end(); // this thing knows it did work now
xar2.end(); //  internally this thing knows it did not do work now
xars.sort(); // xar1 returns 0, xar2 returns -1
xar2.prepare() // RDONLY
xar1.commit1PC()

>             Project: WildFly
>          Issue Type: Bug
>          Components: EJB, Transactions
>    Affects Versions: 12.0.0.Final
>            Reporter: Jörg Bäsner
>            Priority: Major
>              Labels: downstream_dependency
>
> Scenario:
> - server-1 (intermediary)
> -- Running standalone profile
> -- Has a remote-outbound-connection pointing at server-2 through server-2's public IP address
> -- Intermediary bean need to lookup the Target bean in server-2 and also inject the {{TransactionManager}}
> -- Intermediary bean need to enlist a _dummy_ XAResource 
> - server-2 (target)
> -- disable {{JBOSS-LOCAL-USER}} auth
> -- Target bean needs to be annotated with {{@REQUIRES_NEW}} (important)
> - Standalone EJB client invokes an intermediary bean server-1, which as a result invokes target  bean on server-2. 
> The _dummy_ XAResource should log in the {{commit}} method whether one-phase optimization is being used like:
> {code}
>     @Override
>     public void commit(Xid arg0, boolean onePhaseOptim) throws XAException {
>         logger.info("-- Committing in the client resource. One-phase optimisation is: " + onePhaseOptim + " --"
>                 + (onePhaseOptim ? "" : " -> TWO-PHASE COMMIT !!!"));
>     }
> {code}
> In this scenario it is expected that the one-phase optimization is being used!
