Proof step 9 from proof nonnullrefs-in (previous step)

r = r1, ∀ r0. r0 ∈ vals0 .nonnullrefs ↔ r0 ≠ jvmref ∧ (∃ m. vals0[m] = refval(r0) ∧ m < # vals0) ⊦ r1 = jvmref, r = r1 ↔ r ≠ jvmref ∧ (∃ m. (refval(r1) ' + vals0)[m] = refval(r) ∧ ¬ # vals0 < m), r ∈ vals0 .nonnullrefs

Proof step 8:
∀ r0. r0 ∈ vals0 .nonnullrefs ↔ r0 ≠ jvmref ∧ (∃ m. vals0[m] = refval(r0) ∧ m < # vals0) ⊦ r1 = jvmref, r1 ∈ vals0 .nonnullrefs, ∃ m. (refval(r1) ' + vals0)[m] = refval(r1) ∧ ¬ # vals0 < m
