If you are referring to the diference between these:

	#define CONSTANT_String                 8
	#define CONSTANT_ResolvedString         (16+CONSTANT_String)

then the difference is that the value of a CONSTANT_ResolvedString
is a reference to an intern'ed java.lang.String object, while the
value of a CONSTANT_String is a pointer to a Utf8Const.  The latter
is not interned, and is the value of a CONSTANT_Utf8 constant.
The distinction is useful for two reasons:
1) We don't need to allocate and intern an actual java.lang.String
until the class is actually 'prepared'.
2) An ahead-of-time compiler (i.e. gcc) can create a pre-allocated
Utf8Constant in static data memory, but cannot create of a
pre-allocated java.lang.String object (because of separate compilation
making it difficult to properly intern a string in advance).
