Here I have dragged the CLASSY_THING : Thing Property out of the attributes compartment of javavariables.Main to create an Association with it as the Property end. I have then also selected the option [All] under Symbol Properties >  Show Association Ends as Attributes:

Now one can see the Property in both the attributes compartment as a Property end of an Association !

BTW one can also use a "callout" into a Note to get at information not otherwise displayed on an Association end.
