Proof step 19 from proof validstatfields-initundone (previous step)

mkfs(class0, ty, fieldvar) ' ∈ statfields(class), statfields(class) = [] ∨ tdname∃(str, class) ⊦ initdone(class, st), (initdone(class0, st) → validfield(str, jvmref, mkfs(class0, ty, fieldvar) ', st)) ∧ tdname∃(str, class0) ∧ mkfs(class0, ty, fieldvar) ' ∈ statfields(class0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 18:
⊦ class ≠ class0 → ¬ mkfs(class0, ty, fieldvar) ' ∈ statfields(class)

Rule argument
