    NullPointerException When Re-joining a Cluster

    wayne baylor Apprentice

      I'm running JBossAS 4.2.0GA and using the farm-service.

      I have clustered two app. servers and the farming is working for the most part, but I get a NPE when the following sequence happens:

      1) Kill one of the servers manually (server A).
      2) Manually remove all archives in the farm/ dir of server A.
      3) Restart server A
      4) server A pulls deployments
      5) server A attempts to deploy, gets NPE

      Here's a partial stack trace from the log:

      Any idea what's causing this?
