Paul Gale created AMQ-4674:
------------------------------

             Summary: ActiveMQ 5.x does not support the notion of a 
grace-period for heart beats as supported by the STOMP protocol
                 Key: AMQ-4674
                 URL: https://issues.apache.org/jira/browse/AMQ-4674
             Project: ActiveMQ
          Issue Type: New Feature
    Affects Versions: 5.8.0
            Reporter: Paul Gale
             Fix For: NEEDS_REVIEWED


Regarding the configuration of heart beating the STOMP protocol spec states:

    "- because of timing inaccuracies, the receiver SHOULD be tolerant and take 
into account an error margin"

However, it appears that ActiveMQ 5.x is not tolerant of any error margin. 

Despite the fact that the spec says SHOULD rather than MUST it would make the 
implementation of STOMP clients easier if the error margin was published.

Apparently Apollo supports an error margin of 1.5x the configured heart beat. 
If it could be made configurable that would be even better!
