Proof step 25 from proof validrefs-newref (previous step)

¬ (r0 ≠ jvmref ∧ (¬ is_valid_ref(str, r0, st) ∨ ¬ st[r0 -- _type] .type ≤ ty)), validrefs(str, r0 ' + acc, ty, st), newref(r, st), ∀ str, ty, st, r. validrefs(str, acc, ty, st) ∧ r ∈ acc ∧ newref(r, st) → r = jvmref ⊦ r0 = jvmref, r = jvmref, r ≠ r0 ∧ ¬ r ∈ acc

And obtained the following new goals

Proof step 24:
validrefs(str, r0 ' + acc, ty, st), newref(r, st), is_valid_ref(str, r0, st), st[r0 -- _type] .type ≤ ty, r ∈ acc, ∀ str, ty, st, r. validrefs(str, acc, ty, st) ∧ r ∈ acc ∧ newref(r, st) → r = jvmref ⊦ r0 = jvmref, r = jvmref, r = r0
