      Description

      Not sure this is a bug, more likely a logging issue in Drools, however IMO it should be at least documented and eventually the log severity might be changed.

      Detailed description of the QS I use is here:
      https://docspace.corp.redhat.com/clearspace/docs/DOC-27544

      The BRP uses a rule agent to get a rule package. This rule agent is configured to maintain a local cache, just in case the BRMS server goes down.
      When I run the QS for the first time, the rule package is downloaded and put in to the cache dir. So far so good.
      When I stop the BRMS server, I would expect that the rule agent grabs the local cached copy letting me know with an INFO, eventually WARN message, but what I get are following messages:

      ====================================

      Just to be clear, the local cache is used successfully, it's just the logging at the ERROR level and stack trace, that might cause confusion.
