Hi. Just stumbled across this one when I tried to use STRING-EQUAL to compare a value I received via JINTERFACE-IMPLEMENTATION. Now, it appears to be very simple to allow the expression (string (jnew "java.lang.String" "foo")) by overriding STRING() in JavaObject and checking if obj is a (java) String. What do you think?
