> Currently the CMS Message interface restricts the user from calling a get method on a
property that is not of the type that matches the call, for instance call getIntProperty when
the value contained internally is a long would throw an exception.  To make this interface
more flexible and to allow for stomp support to work properly in the new architecture it is
necessary to support conversion of all the elements in the properties to a string type.  Since
this happens automatically as a result of implementing the standard JMS conversion table it
makes sense to do this in a way that's allows the CMS interface implementation to benefit
from it as well.

> Message properties support the following conversion table. The marked cases must be supported.
The unmarked cases must throw a JMSException. The String-to-primitive conversions may throw
a runtime exception if the primitive's valueOf method does not accept the String as a valid
representation of the primitive.
