--------------------------------------

             Summary: Track SRAs that are started in the context of an LRA
                 Key: JBTM-2945
                 URL: https://issues.jboss.org/browse/JBTM-2945
             Project: JBoss Transaction Manager
          Issue Type: Enhancement
          Components: LRA
    Affects Versions: 5.7.0.Final
            Reporter: Michael Musgrove
            Assignee: Michael Musgrove
             Fix For: 5.later


Often an LRA is built up from a number of individual actions performed by the
participants enlisted with the LRA. These participants may use the ACID
guarantees that an SRA provides in order to fulfil the requisite compensatory
and completion actions when the LRA is terminated. To support this requirement
when an SRA is started in the context of an LRA (either by annotating a method
with both the @LRA and @SRA annotations or by starting an SRA via the client
API when an LRA is already active) then the SRA will be automatically
associated with the LRA. The following interface is provided for querying which
LRAs and SRAs are associated with each other (in a one to many relationship):

{code}
public interface LRAToSRA {
  /**
   * return all the SRAs running in the context of the given LRA
   */
  List<SRA> getAssociatedSRAs(URL lraId};

  /**
   * see if an LRA is associated with the give SRA
   */
  URL getAssociatedLRA(URL sraId);
}
{code}

Questions:
   - should @Compensate and @Complete block until all associated SRAs have finished
   - when an LRA is closed or cancelled should any active SRAs be automatically be committed or rolled back.
