      Description

      Hi,
      we have a problem with the removing an inactive durable subscription after certain period of inactivity.
      It throws java.lang.ClassCastException.

      schedulerSupport="true" offlineDurableSubscriberTimeout="60000" offlineDurableSubscriberTaskSchedule="30000">

      Log:
