Technically it may be that the java.instrument module is not observable 
but saying that it may not be in the run-time image is probably clearer 
to the clearer. The main thing is to connect it to the java.instrument 
module, other details are useful too, say where someone has a corrupt 
installation or the wrong permissions on the library.
