Proof step 9 from proof isarray-put-samefield-01 (previous step)

st[r -- _type] = typeval(ty1), ty1 = mkarraytype(ty0), r ∈ st, r -- mkfs(class, ty, fieldvar) ' ∈ st, oktype(st[r -- mkfs(class, ty, fieldvar) '], ty, st), oktype(val, ty, st), r -- _type ∈ st, is_typevalue(st[r -- _type]), okarray(r, ty0, st[r -- mkfs(class, ty, fieldvar) ', val]) ⊦ mkfs(class, ty, fieldvar) ' = _length, mkfs(class, ty, fieldvar) ' = _type, r = jvmref, is_array(r, st)

And obtained the following new goals

Proof step 8:
st[r -- _type] = typeval(mkarraytype(ty0)), okarray(r, ty0, st[r -- mkfs(class, ty, fieldvar) ', val]), r -- _type ∈ st, oktype(val, ty, st), oktype(st[r -- mkfs(class, ty, fieldvar) '], ty, st), r -- mkfs(class, ty, fieldvar) ' ∈ st, r ∈ st ⊦ r = jvmref, mkfs(class, ty, fieldvar) ' = _type, mkfs(class, ty, fieldvar) ' = _length, is_array(r, st)
