> Our implementation of javax.jms.MapMessage is org.jboss.jms.message.JBossMapMessage.  Its setObject is:
>    public void setObject(String name, Object value) throws JMSException
>    {
>       checkName(name);
>       if (value instanceof Boolean)
>          ((Map)getPayload()).put(name, value);
>       else if (value instanceof Byte)
>          ((Map)getPayload()).put(name, value);
>       else if (value instanceof Short)
>          ((Map)getPayload()).put(name, value);
>       else if (value instanceof Character)
>          ((Map)getPayload()).put(name, value);
>       else if (value instanceof Integer)
>          ((Map)getPayload()).put(name, value);
>       else if (value instanceof Long)
>          ((Map)getPayload()).put(name, value);
>       else if (value instanceof Float)
>          ((Map)getPayload()).put(name, value);
>       else if (value instanceof Double)
>          ((Map)getPayload()).put(name, value);
>       else if (value instanceof String)
>          ((Map)getPayload()).put(name, value);
>       else if (value instanceof byte[])
>          ((Map)getPayload()).put(name, ((byte[]) value).clone());
>       else
>          throw new MessageFormatException("Invalid object type.");
>    }
> Setting a null value will result in a MessageFormatException since instanceof returns false on nulls.  Although the JMS spec doesn't indicate its necessity, I think we should support setting null values (e.g. javax.jms.MapMessage.setObject("name", null)) as this is a convenience method support both by WebLogic and WebSphere.
