-----------------------------------------
Hi,
I'm having a similar problem when I try to set a Mail attribute value to an
instance of one of my own classes. According to the JavaDoc
http://docs.oracle.com/javaee/5/api/javax/jms/Message.html,
"The setObjectProperty method accepts values of class Boolean, Byte, Short,
Integer, Long, Float, Double, and String. An attempt to use any other class
must throw a JMSException.
The getObjectProperty method only returns values of class Boolean, Byte, Short,
Integer, Long, Float, Double, and String."
I'm not getting a JMSException, but I'm getting a String back when trying to
read the attribute, just as in the description of this issue. The SVN-commit to
this issue looks like it assumes that set-/getObjectProperty can work with any
Serializable, not just Boolean, Byte, ..., String. Isn't that a dangerous
assumption?
Thanks!
