Should be "an observable compilation unit containing a ...". Per 7.3, 
once you've decided a compilation unit is observable, then if it 
contains a module declaration you're required to associate the c.u. with 
the declared module and not with (say) java.base. And if the c.u. is not 
observable then associated-with is moot.
