Proof step 30 from proof validrefs-newref (previous step)

∀ str, ty, st, r. validrefs(str, acc, ty, st) ∧ r ∈ acc ∧ newref(r, st) → r = jvmref, validrefs(str, r0 + acc, ty, st), r ∈ r0 + acc, newref(r, st) ⊦ r = jvmref

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 29:
newref(r, st), validrefs(str, r0 ' + acc, ty, st), ∀ str, ty, st, r. validrefs(str, acc, ty, st) ∧ r ∈ acc ∧ newref(r, st) → r = jvmref ⊦ r = jvmref, r ≠ r0 ∧ ¬ r ∈ acc
