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

             Summary: Generic operation tasks should be able to return specific results
                 Key: OAK-1863
                 URL: https://issues.apache.org/jira/browse/OAK-1863
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: core
            Reporter: Michael Dürig
            Assignee: Michael Dürig
             Fix For: 1.1


The generic interface for operation management tasks added with OAK-1160 does so far not provide a way for specific tasks to return a value apart from a genetic status. With the consistency checking we are starting to add (OAK-1448) such a needs start to arise. 

To address this I propose to change type of the tasks that can be passed to the constructor of {{ManagementOperation}}. The result type of the task (i.e. {{Callable}}) should change from {{Long}} to some generic container, which would carry the result of the task.
