Proof step 12 from proof validsubset-put-statfield (previous step)

junkref(str, r, st0[jvmref -- sk, val]), r ∈ st0, ∀ r. ¬ r ∈ st ∧ r ∈ st0 → ¬ junkref(str, r, st0), ∀ r, ty. validref(str, r, ty, st) → validref(str, r, ty, st0) ⊦ r = jvmref, r ∈ st

Heuristic quantifier closing applied rule all left

And obtained the following new goals

Proof step 11:
⊦ junkref(str, r, st[jvmref -- sk, val]) → junkref(str, r, st)

Rule argument
