      JBoss Version ::
      ==========

      22:06:37,109 INFO [Server] Release ID: JBoss [Matrix2] 4.0.0DR2 (build: CVSTag=
      JBoss_4_0_0_DR2 date=200307030107)

      Relevant parts of Jboss-service.xml
      =======================

      <!-- Obj Mgr -->



      <!-- Obj Mgr2 -->




      <!-- Object A -->

      <depends optional-attribute-name="ManagerObj">MyDomain:name=objmgr
      <depends optional-attribute-name="MangerObj2">MyDomain:name=objmgr2



      <!-- Object B -->

      <depends optional-attribute-name="ManagerObj">MyDomain:name=objmgr
      <depends optional-attribute-name="MangerObj2">MyDomain:name=objmgr2



      Seems like its something to do with the same dependencies of Object A and Object B as object A can deployed if Object B is removed from the xml and vice-versa.

      Any clues ?
