    4.13: UnsupportedOperationException on mergeInventoryReport() in log continuously

    Stian Lund Expert

      Hi,

      after upgrading to 4.13 an UnsupportedOperationException gets thrown in the log on a regular basis. Seems to be thrown every 10 minutes and relating to agent inventory reports.

       

      I can easily make a BZ, just want to make sure it's now a known error (couldn't find any on BZ).

       

      Not sure if maybe related to operation history not being purged?

       

      Below is the full stack trace, seem to be two different exceptions with same error at about the same time.

       

      (It's a big'un)
