The java support for spread was originally written for Java 1.0.2 and was 
updated to use some java 1.1 features a bit later. Since then we have not
used any additional java features, just fixed bugs, updated the protocol
implementation, or added new methods. So it should work on 1.1. 

It is mainly tested on Suns JVM, but I know of several people using it
extensively with java programs on Windows. I do not know which jvm they
are using and they might be using Sun's JVM for Windows and not Microsofts
JVM.
