Proof step 6 from proof validrefs-superset-junkref (conclusion)

⊦ validrefs(str, r ' + refs, ty, st0) ∧ r0 ∈ refs ∧ newref(r0, st) ∧ st ⊆ st0 → junkref(str, r, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
validrefs(str, r ' + refs, ty, st0), r0 ∈ refs, newref(r0, st), st ⊆ st0 ⊦ r0 = jvmref, junkref(str, r, st)

Rule argument
