Support multiple one-phase resources
------------------------------------

                 Key: JBTM-169
                 URL: http://jira.jboss.com/jira/browse/JBTM-169
             Project: JBoss Transaction Manager
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: Documentation, JTA Implementation
    Affects Versions: 4.2.2
            Reporter: Mark Little
         Assigned To: Mark Little
             Fix For: 4.4


JBossTM allowed multiple one-phase only resources to be enlisted with the same JTA transaction. JBossTS supports the LRCO, which only allows a single one-phase resource to be enlisted. This difference may cause problems for some people migrating from JBossTM to JBossTS. However, it is an unsafe mode of operation and we should discourage people from using transactions in this way: it can lead to inconsistent/corrupted data in the presence of failures.

We will add a switch to enable this capability. It will be disabled by default. People must actively enable this capability and in the process of doing so will be refered to the documentation which will outline the problems they may face by doing so. Furthermore, when a JTA transaction sees more than one 1-phase resource, it will issue a warning.
