The JVM provides no ability to do anything with System.loadLibrary from multiple 
class loaders.  So, you have to find a way to load it from a single class 
loader, that all service instances can see.

Another way would be to virtualize access to the serial ports by creating a 
single service instance that is a monitor for access to the ports.  Then, have 
your other services instances (MonitorService) use that service to access the 
ports.  Then, everything is a "service" inside of com.sun.jini.start.

To some degree, it seems like only a single service needed.  You could send out 
a "smart proxy" to the client for access to a specific port.
