Proof step 11 from proof nonnullrefs-in-firstoc (previous step)

⊦ r = jvmref, r0 = jvmref, r = r0, refval(r) ∈ vals, ∃ vals3, vals2. refval(r0) ' + vals + refval(r) ' + vals1 = vals3 + refval(r) ' + vals2 ∧ ¬ refval(r) ∈ vals3

Heuristic quantifier closing applied rule exists right

And closed the goal!

Rule argument

[EXRARG : pos: right 5, [QUANTTERMLIST : (refval(r0) ' + vals, vals1)]]
