I've opened separate bug (and did not update Bug 655187) as I get the above error even without bundle being uploaded.

The exception about failure to delete/truncate spool was fixed by putting a check in place that checked the existence of the spool file.

The error messages about invalid inventory (or availability) reports still appear, but their content was updated to state the fact that if such error happens right after platform removal, it can be ignored.

    BZ 657232
    * Don't throw NPE while destroying an agent on the server-side
      if there is no command spool file name defined.
    * Improve the error messages during intermittent confusion of the server
      and agent after platform removal.
