Proof step 15 from proof junkref-put-null (previous step)

is_reftype(fs .type), junkref(str, r, st[r0 -- fs ', refval(jvmref)]) ⊦ junkref(str, r, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 14:
fs = mkfs(class, ty, fieldvar), is_reftype(ty), junkref(str, r, st[r0 -- fs ', refval(jvmref)]) ⊦ junkref(str, r, st)

Rule argument

[speclemmaarg: , class = fs .class ∧ ty = fs .type ∧ fieldvar = fs .field ↔ fs = mkfs(class, ty, fieldvar) ,[fs, class, ty, fieldvar] → [fs, class, ty, fieldvar] ,T ,fieldspec , ,elim ]
