Description

Here is related code from BackupUtils#checkTargetDir:

      String expMsg = e.getMessage();
      String newMsg = null;
      if (expMsg.contains("No FileSystem for scheme")) {
        newMsg =
            "Unsupported filesystem scheme found in the backup target url. Error Message: "
                + newMsg;

I think the intention was to concatenate expMsg at the end of newMsg.
