Proof step 11:
r -- mkfs(class, ty, fieldvar) ' ∈ st, okval(st[r -- mkfs(class, ty, fieldvar) '], ty), okval(val, ty), r ∈ st, r -- _type ∈ st, is_typevalue(st[r -- _type]), is_classtype(st[r -- _type] .type), is_obj(r, st[r -- _type] .type .class, st[r -- mkfs(class, ty, fieldvar) ', val]) ⊦ mkfs(class, ty, fieldvar) ' = _type, r = jvmref, is_obj(r, st)
