Incompatible signature change in HATarget
-----------------------------------------

                 Key: JBCLUSTER-282
                 URL: https://jira.jboss.org/browse/JBCLUSTER-282
             Project: JBoss Clustering
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: HA-Server-API
            Reporter: Brian Stansberry
            Assignee: Brian Stansberry
             Fix For: HA-Server-API 1.2.0.Final , HA-Server-API 2.0.0.Final


The 2.0.0.Alpha series changed the return type of HATarget.getReplicants from ArrayList to List. This is breaking EJB3 (see EJBTHREE-2112) even though they actually handle the return value as a List.

EJB3 needs a compatible interface for the 1.x series (for their usage in EAP 5.x) and the 2.x series (for AS 6 and later). So, solution is, in ha-server-api trunk and in a 1.2 branch:

1) Restore ArrayList as the getReplicants() return type.
2) Add public List<?> getReplicantList()
3) Deprecate getReplicants()
4) Release a 2.0.0.Alpha5 and a 1.2.0.Final
5) Move AS trunk to 2.0.0.Alpha5 so EJB3 testsuite can work
6) At some date, remove all AS trunk usage of the deprecated method
7) When the JBPAPP_5_1 branch is available for commits again, move it to 1.2.0
8) THEN move ejb3-proxy-clustered to 1.2.0, and have it use the new method.
