I don't have a complete answer for you, but here's an additional
data point that might help:

$ kawa --lisp
#|kawa:1|# <gnu.lists.FString>
<unknown>: warning - no declaration seen for <gnu.lists.FString>
unbound location <gnu.lists.FString>
         at gnu.mapping.Location.get(Location.java:67)
         at atInteractiveLevel$1.run(stdin)
         at gnu.expr.ModuleExp.evalModule2(ModuleExp.java:299)
         at gnu.expr.ModuleExp.evalModule(ModuleExp.java:200)
         at kawa.Shell.run(Shell.java:279)
         at kawa.Shell.run(Shell.java:194)
         at kawa.Shell.run(Shell.java:175)
         at kawa.repl.main(repl.java:884)
#|kawa:2|# gnu.lists.FString
class gnu.lists.FString
#|kawa:3|# ^D

So, check where Kawa handles class literals enclosed in angle brackets.
Maybe it's in Scheme-only code (and therefore another candidate for
refactoring).

Right, I think that's already in there due to the

     LocationEnumeration e = Scheme.builtin().enumerateAllLocations();
     while (e.hasMoreElements())
       {
         importLocation(e.nextLocation());
       }

at the top of initLisp().
