The container serializes calls to each message-driven bean instance. Most containers will support many instances of a message-driven bean executing concurrently; however, each instance sees only a serialized sequence of method calls. Therefore, a message-driven bean does not have to be coded as reentrant.

I read this statement multiple times and could not understand. can any one please explain this.
