The new JMX based tooling for browsing abstract records does not display the particular type of a heuristic when it's available.
There is a comment in the javadoc for AbstractRecord which seems to indicate that the particular kind of heuristic may be available:
HeuristicInformation contains a method getHeuristicType() which looks like it may report the particular kind of heuristic.:
This JIRA is asking for value() object to be consulted to see if it contains an instance of HeuristicInformation and if so to report it in the JBX MBean corresponding to the AR.
Note that such a change would only affect 3rd party implementers of ARs (since our own code does not set this field).
