Proof step 16 from proof isobj-putbar (previous step)

st[r -- _type] = typeval(mkclasstype(class)), is_obj(r, class, putByteArray(bytes, r1, i, st)), r -- _type ∈ st, r ∈ st ⊦ r = jvmref, r ≠ jvmref ∧ (r -- _type) × typeval(mkclasstype(class)) ∈ st ∧ goodfieldsandtypes(r, instfields(class), st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 15:
st[r -- _type] = typeval(mkclasstype(class)), is_obj(r, class, putByteArray(bytes, r1, i, st)), r -- _type ∈ st, r ∈ st ⊦ r = jvmref, goodfieldsandtypes(r, instfields(class), st)
