             Summary: Bug in SPI for tracking transaction state association changes
                 Key: JBTM-2863
                 URL: https://issues.jboss.org/browse/JBTM-2863
             Project: JBoss Transaction Manager
          Issue Type: Bug
          Components: SPI
    Affects Versions: 5.5.3.Final
            Reporter: Michael Musgrove
            Assignee: Michael Musgrove
             Fix For: 5.later

JBTM-2343 introduced a feature for observing transaction state changes (requested by JPA). Listeners register interest in particular events (ASSOCIATED and DISASSOCIATING). However, BaseTransactionManagerDelegate will notify listeners for either event even if they only subscribed for one of them. For example if a listener subscribes for thread to transaction associations only it will also receive disassociation notifications.

In addition, the current event types are restricted to a single java enum (org.jboss.tm.listener.EventType). Since java enums are not extensible the solution needs to be tweaked so that we can easily add new event types.
