>Description:
According to section 12.4.1 of the JVM, a class or
interface shouldn't be initialized if a field is
passively referenced; this includes references to
"static final" (or equiv.) fields whose value is a
compile-time constant expression.  The latter is
defined (section 15.27) to include Strings.

We don't seem to handle this at all.

I checked in the "stringconst.java" test which demonstrates
the bug.  However, that is just one instance; I suspect
there are others.
