Modified: src/main/org/jboss/invocation Invocation.java
Log:
The invocation now uses the 3 maps to store information
TRANSIENT is information that should not travel and is just used on the client side
AS-IS is a map that can travel AS-IS with respect to serialization and will be
deserialized by any VM (JDK classes go there)
PAYLOAD is the map that will get serialized in the MARSHALLED STUFF SINCE IT IS
application specific
