       * gnu/java/rmi/server/UnicastConnectionManager.java
       (startScavenger): Set the client connection manager to daemon
       state because it may block clients until TIMEOUT is reached
       when they are exiting.

       * gnu/java/rmi/RMIVoidValue.java: New file for a class representing
       a void return.

       * gnu/java/rmi/server/UnicastRemoteCall.java
       (DummyOutputStream): Add a boolean before each written field to
       know whether it is a primitive.
       (releaseOutputStream): Flush parameters at write time.

       * gnu/java/rmi/server/UnicastServerRef.java
       (incomingMessageCall): Return a RMIVoidValue if no value is to be
       returned.

       * gnu/java/rmi/server/UnicastServer.java
       (incomingMessageCall): Do not write a returned object if it is
       a RMIVoidValue.

       * gnu/java/rmi/server/Makefile.am (EXTRA_DIST): Add RMIVoidValue.java.
