             Summary: HASingleton custom election policy isn't called with only one member
                 Key: JBCLUSTER-297
                 URL: https://issues.jboss.org/browse/JBCLUSTER-297
             Project: JBoss Clustering
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: HA-Server-API
    Affects Versions: HA-Server-API 1.2.0.Final 
            Reporter: James Livingston
            Assignee: Paul Ferraro


This is a backport of AS7-3295 to 5.x's clustering code.

A custom HASingleton election policy is not called when there is only one member in the cluster. The hard-coded check for size == 1 should be removed, and the custom policy should always be called.

This bug prevents policies that do not start HASingletons if a quorum is not reached.
