Proof step 174 from proof addarray-disjoint-nosharing-01 (previous step)

∃ sks1, sks2. fits(r, sks1, addarray(r, ty, vals, st)) ∧ fits(r, sks2, addarray(r, ty, vals, st)) ∧ sks1 ≠ sks2 ∧ sks1 ≠ [] ∧ sks2 ≠ [] ∧ (addarray(r, ty, vals, st)[r -- sks1]) .refval ≠ jvmref ∧ (addarray(r, ty, vals, st)[r -- sks1]) = (addarray(r, ty, vals, st)[r -- sks2]), disjoint(str, vals .nonnullrefs, st), validreflist(str, vals, ty, st), newref(r, st) ⊦ r = jvmref, dups(vals .nonnullrefs), hasSharing(vals .nonnullrefs, st)

And obtained the following new goals

Proof step 173:
(addarray(r, ty, vals, st)[r -- sks0]) = (addarray(r, ty, vals, st)[r -- sks]), fits(r, sks0, addarray(r, ty, vals, st)), fits(r, sks, addarray(r, ty, vals, st)), disjoint(str, vals .nonnullrefs, st), validreflist(str, vals, ty, st), newref(r, st) ⊦ r = jvmref, (addarray(r, ty, vals, st)[r -- sks]) .refval = jvmref, sks = [], sks0 = [], sks0 = sks, dups(vals .nonnullrefs), hasSharing(vals .nonnullrefs, st)
