The method documentation refers to the notion of "strongly reachable” in the j.l.ref package doc (I should update to link directly to that). In effect it’s an operation on potential referents that relates to reachability, garbage collection and finalization.

As all Runtime methods are instance methods the usage here would be a
bit awkward. Personally I thought reference was a very suitable location
for a reachability-related method.
