Proof step 62 from proof junkrefs-put-null (conclusion)

⊦ ¬ junkrefs(str, refs, ty, st) ∧ is_obj(r, st) ∧ is_reftype(fs .type) ∧ fs ' ∈ instfields(st[r -- _type] .type .class) → ¬ junkrefs(str, refs, ty, st[r -- fs ', refval(jvmref)])

User applied rule structural induction

And obtained the following new goals

Proof step 1:
⊦ ¬ junkrefs(str, [], ty, st)
Proof step 61:
∀ str, ty, st, r, fs. ¬ junkrefs(str, acc, ty, st) ∧ is_obj(r, st) ∧ is_reftype(fs .type) ∧ fs ' ∈ instfields(st[r -- _type] .type .class) → ¬ junkrefs(str, acc, ty, st[r -- fs ', refval(jvmref)]) ⊦ ¬ junkrefs(str, r0 + acc, ty, st) ∧ is_obj(r, st) ∧ is_reftype(fs .type) ∧ fs ' ∈ instfields(st[r -- _type] .type .class) → ¬ junkrefs(str, r0 + acc, ty, st[r -- fs ', refval(jvmref)])
