Proof step 38:
mkfs(class, ty0, fieldvar) ' ∈ statfields(class0), compatmode(str, st), compatrefs(str, st), compat(str, val, ty0, st), initdone(class0, st), compatfields(str, jvmref, statfields(class0), st), class∃(str, class0) ∨ interface∃(str, class0) ⊦ mkfs(class, ty0, fieldvar) ' = _length, ty0 = void_type, compat(str, val, ty0, st[jvmref -- mkfs(class, ty0, fieldvar) ', val])
