Proof step 37 from proof validrefs-addobj (previous step)

r0 ≠ jvmref, validrefs(str, r0 ' + acc, ty, addobj(r, class, fis, st)), ∀ str, ty, r, class, fis, st. validrefs(str, acc, ty, addobj(r, class, fis, st)) → validrefs(str, acc, ty, st) ∨ r ∈ acc ⊦ r = r0, validrefs(str, r0 ' + acc, ty, st), r ∈ acc

And obtained the following new goals

Proof step 36:
validrefs(str, r0 ' + acc, ty, addobj(r, class, fis, st)), ∀ str, ty, r, class, fis, st. validrefs(str, acc, ty, addobj(r, class, fis, st)) → validrefs(str, acc, ty, st) ∨ r ∈ acc ⊦ r0 = jvmref, r = r0, r ∈ acc, validrefs(str, r0 ' + acc, ty, st)
