      Description

      We have a script that runs GC periodically by hitting "/monitoring?action=gc".

      We upgraded to the latest version of the monitoring plugin and Jenkins and we are now getting the following exception in the logs:

      /monitoring?action=gc
      java.lang.IllegalStateException: Response is committed

      It looks benign, but it's something that we haven't seen before.

      I can't tell if the "/monitoring?action=gc" is actually working, but it looks like it is.
      If it is not, I'll upgrade the severity of this ticket.
