Proof step 5 from proof newrefs-null (previous step)

∀ st. ¬ jvmref ∈ newref_list(m, st), jvmref ∈ newref_list(m +1, st) ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ newref_list(n + 1, st) = newref(st) + newref_list(n, st[newref(st) -- 0 ', noval])
Proof step 3:
⊦ newref(st) ≠ jvmref
Proof step 4:
jvmref ∈ newref_list(m, st[newref(st) -- 0 ', noval]), ∀ st. ¬ jvmref ∈ newref_list(m, st) ⊦

Rule argument
