Proof step 10 from proof isobj-addarray-other (previous step)

st[r -- _type] = typeval(ty), ty = mkclasstype(class), r ∈ st, is_obj(r, class, st), is_typevalue(st[r -- _type]), r -- _type ∈ st ⊦ r = jvmref, r = r0, is_obj(r, addarray(r0, ty0, vals, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 9:
st[r -- _type] = typeval(mkclasstype(class)), r -- _type ∈ st, is_obj(r, class, st), r ∈ st ⊦ r = r0, r = jvmref, is_obj(r, addarray(r0, ty0, vals, st))
