Interoperability Patch for RMI + RMIspy tool

Sun Jan 4 16:14:00 GMT 2004

I have made changes to libjava-rmi to improve interoperability with other java
implementations. There were only little differences in the protocol, 
but they caused a lot of problems. I have written a 'rmispy'-tool to watch the raw-streams 
of the rmi conversation as hex/ascii (it hooks into RMISocketFactory). The interoperability 
tests and the rmispy tool can be downloaded from:
http://www.scheinwelt.at/~norbertf/gcj/tests/rmi_interop_spy3.tar.gz
The patch (attached) repairs the following things:
* When reusing XXXObjectStream objects: 
Magic number & version have to be written/collected every time we send/receive
one or more java objects over the wire.
(Libgcj was only sending/collecting the magic number & version bytes at the beginning of a 'conversation' which was different
from the other javas)
* Void return-values are now beeing handled like in the other java. 
(void means no field is written to the stream)
* It also contains the patch from my last mail.
