Proof step 8 from proof validstatfield-subset (previous step)

sk = fs ', fs = mkfs(class, ty, fieldvar), is_fskey(sk), validstatfield(str, sk, st), st ⊆ st0, initdone(class, st0), initdone(class, st) ⊦ validfield(str, jvmref, sk, st0) ∧ tdname∃(str, class) ∧ sk ∈ statfields(class)

And obtained the following new goals

Proof step 7:
