The one problem is that UNO "named pipe" (i.e., 
--accept=pipe,name=foo;urp) communication, even from within a pure Java 
environment, needs some native code (jpipe JNI library) which obviously 
needs to be available in the format of the JVM process's architecture. 
Using TCP sockets (i.e., --accept=socket,host=localhost,port=12345;urp) 
should work around that problem.
