     The former.  That's what it said; why should you
disbelieve what it says about its own expectations?  ;-)

     Was its expectation reasonable?  I think so, because
given the prefix `if ( true ) int' I can imagine no other
continuation than `. class' that could be part of a valid
parse, as in `if (true) int.class.getClassLoader();'.

     Can you think of any other valid continuations?
