Proof step 16 from proof isobj-addobj-01 (previous step)

st[r -- _type] = typeval(mkclasstype(class)), goodfieldsandtypes(r, instfields(class), st), newref(r0, st), r -- _type ∈ st, r ∈ st ⊦ r0 = jvmref, r = jvmref, r ≠ jvmref ∧ (r -- _type) × typeval(mkclasstype(class)) ∈ addobj(r0, class0, fis, st) ∧ goodfieldsandtypes(r, instfields(class), addobj(r0, class0, fis, st))

And obtained the following new goals

Proof step 3:
⊦ rk ∈ st → rk ∈ addobj(r, class1, fis, st)
Proof step 4:
⊦ r0 ∈ st ∧ newref(r, st) → (addobj(r, class1, fis, st)[r0 -- sk]) = st[r0 -- sk]
Proof step 15:
st[r -- _type] = typeval(mkclasstype(class)), goodfieldsandtypes(r, instfields(class), st), newref(r0, st), r -- _type ∈ st, r ∈ st ⊦ r0 = jvmref, r = jvmref, goodfieldsandtypes(r, instfields(class), addobj(r0, class0, fis, st))
