[Bug libgcj/17979] New: Binary Compatibility: could resolve String references while defining class

[tromey at gcc dot gnu dot org]

In defineclass.cc, we do a pass over the constant pool
and turn JV_CONSTANT_String references into _Jv_Utf8Const
objects.  Later, during linking, these are turned into
real String instances.  We could just as easily create
real Strings when defining the class and reduce the amount
of work to be done during linking.

On the one hand this involves more space overhead for classes
which are not used (most string constants are ASCII, which
is represented more compactly in a Utf8Const).  On the other
hand, the utf8const is garbage after linking, some String constants
are common (these are always interned, so these would be shared),
and usually string constants are short anyway (so the savings
is probably not significant).

Is this related to PR 1259 at all?

I think PR 1259 relates to deficiencies in the compiler,
not the runtime (or at least not this part of the runtime).
This PR refers to a minor possible optimization when defining
an interpreted class; it doesn't affect whether or when
other classes are initialized.
