Keith Wall commented on QPID-3710:
----------------------------------
I don't think this is a defect. java.util.Date is not a supported datatype
within a MapMessage.
The JMS specification defines a map message as "a message whose body contains a
set of name-value pairs where names are Strings and values are Java primitive
types.". Qpid goes further and supports other data-types beyond those required
for JMS, but java.util.Date is not part of the extension.
Please see Programming-In-Apache-Qpid docbook, section 3.4 "JMS MapMessage
Types" for the list of supported data types.
