Proof step 18 from proof isobj-putbar (previous step)

st[r -- _type] = typeval(ty), ty = mkclasstype(class), r ∈ st, r -- _type ∈ st, is_obj(r, class, putByteArray(bytes, r1, i, st)), is_typevalue(st[r -- _type]) ⊦ r = jvmref, is_obj(r, class, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 17:
st[r -- _type] = typeval(mkclasstype(class)), is_obj(r, class, putByteArray(bytes, r1, i, st)), r -- _type ∈ st, r ∈ st ⊦ r = jvmref, is_obj(r, class, st)

Rule argument
