JMS Provider Service
The JMS Provider service enables you to manage the JMS connections and destinations.
This service runs on both the server and dispatcher.
Each working destination (the one with at least one producer/consumer) may take up to sizeLimitInMasterQueue bytes, which means that you should ensure that N * sizeLimitInMasterQueue (where N is the number of expected working destinations) does not exceed the virtual machine heap size.
