Avoid spurious StaleSymbol error in <refinement> members
Refinement classes and their members could give spurious stale symbol errors if the
symbol is loaded in a different run than the classfile containing it. The problem
is that refinement classes do not form part of the scope of their owners. The fix
assumes that refinement classes are always "stillValid".
