Proof step 5 from proof nonnullrefs-in (previous step)

fis0[sk] = refval(r), sk ∈ fis0, ∀ sk, r. fis0[sk] = refval(r) ∧ sk ∈ fis0 → r = jvmref ∨ r ∈ fis0 .vals .nonnullrefs ⊦ r = jvmref, sk = sk0, r0 = jvmref, r = r0, r ∈ fis0 .vals .nonnullrefs

Heuristic quantifier closing applied rule all left

And closed the goal!
