RE: [JBoss-dev] Call optimization caution

[Adrian B. <adr...@jb...>]

So this change has been made anyway???!!!???

"
package org.jboss.invocation;

public class MarshalledValue  extends RemotingMarshalledValue
   implements java.io.Externalizable
"

1) This breaks serialization compatibility with earlier releases
2) It introduces spurious dependencies of projects on remoting
3) Ever here of changing implementation details based on
factories and interfaces?

- MarshalledValue value = new MarshalledValue(object);
+ IMarshalledValue value =
marshalledValueFactory.getMarshalledValue(object);

Then somebody can choose to use old or new.

The more general problem is lack of discussion/notification.
And when there is discussion, it is ignored!
