I refer to this JIRA issue logged by someone in the TCK team:
http://java.net/jira/browse/JMS_SPEC-77
MapMessage.setBytes API discrepancy found in the javadocs
I won't repeat the description here: please follow the link above for a description of the issue and my response. I
hereby propose this is fixed for the Public Draft.
Feel free to reply, but I think this is a straightforward bug in the javadocs and there's no need to read this unless
you're particularly interested.
