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

             Summary: CoreAdminHandler.handleMergeAction generating NullPointerException
                 Key: SOLR-5087
                 URL: https://issues.apache.org/jira/browse/SOLR-5087
             Project: Solr
          Issue Type: Bug
    Affects Versions: 4.4
            Reporter: Patrick Hunt
            Assignee: Patrick Hunt
             Fix For: 5.0, 4.5


CoreAdminHandler.handleMergeAction is generating NullPointerException

If directoryFactory.get(...) in handleMergeAction throws an exception the original error is lost as the finally clause will attempt to clean up and generate an NPE. (notice that "dirsToBeReleased" is pre-allocated with nulls that are not filled in)
