Proof step 17 from proof initsubset-initerror (previous step)

And obtained the following new goals

Proof step 16:
initdone(class3, st), tdname∃(str, class3), mkfs(class0, ty, fieldvar) ' ∈ statfields(class3), tdname∃(str, class0), mkfs(class0, ty, fieldvar) ' ∈ statfields(class0), initdone(class0, st), validfield(str, jvmref, mkfs(class0, ty, fieldvar) ', st) ⊦ initdone(class, st), validfield(str, jvmref, mkfs(class0, ty, fieldvar) ', st[jvmref -- mkfs(class, void_type, `initstate' .field) ', initval(error)])
