You are correct, they are system libs
The libs need to be compiled, linked and installed before the jars 
depending on them can be compiled, then, when everything is in place the 
binding jars can be compiled, these depend on the jars that depend on 
the libs. At runtime the system libraries need to be made visible via 
-Djava.library.path.

DBusConnection.getConnection(DBusConnection.SESSION);

will compile but not run until

-Djava.library.path is set to the location of the system libraries.

Once I figured this out the code compiles and runs.

Actually I really want to use the C glib bindings but the documentation 
is ... difficult so I thought I'd try and get it working in Java first.

Apparently however I'm not smart enough to do that, guess it was just 
luck then :-)

Yes, actually I was surprised that I needed to tell Eclipse where to 
find the system libraries before the code would run, I was hoping that 
dependency was compile time only for the bindings, effectively they 
would encapsulate the platform specific stuff.

I expect it's because I'm not very smart.

No idea what a Sonar report is, should I care?
