             Summary: Tooling does not display the type of a heuristic
                 Key: JBTM-2306
                 URL: https://issues.jboss.org/browse/JBTM-2306
             Project: JBoss Transaction Manager
          Issue Type: Bug
          Components: Tooling
    Affects Versions: 5.0.3
            Reporter: Michael Musgrove
            Assignee: Michael Musgrove
            Priority: Minor
             Fix For: 6.0.0

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:
	 * If this abstract record caused a heuristic then it should return an
	 * object which implements <code>HeuristicInformation</code>
	 * @return <code>Object</code> to be used to order.
	public abstract Object value ();
HeuristicInformation contains a method getHeuristicType() which looks like it may report the particular kind of heuristic.:

public interface HeuristicInformation {
     * The type of heuristic.
     * @return the heuristic type
    public int getHeuristicType();

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).
