Proof step 4 from proof junkrefs-notin-01 (conclusion)

⊦ ¬ r ∈ st → (junkrefs(str, r ' + refs, ty, st) ↔ r ≠ jvmref)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ ¬ junkrefs(str, jvmref ' + refs, ty, st)
Proof step 3:
⊦ r = jvmref, r ∈ st, junkrefs(str, r ' + refs, ty, st)

Rule argument
