Proof step 11 from proof addclass-exactarray (previous step)

⊦ r = jvmref, is_referencevalue(refval(r)) ∧ refval(r) .refval ∈ addclass(class0, fis, st) ∧ ( refval(r) .refval ≠ jvmref → refval(r) .refval -- _type ∈ addclass(class0, fis, st) ∧ is_typevalue(addclass(class0, fis, st)[refval(r) .refval -- _type]) ∧ (addclass(class0, fis, st)[refval(r) .refval -- _type]) .type = mkarraytype(ty)) ∧ r -- _length ∈ addclass(class0, fis, st) ∧ st[r -- _length] = intval(i) ∧ is_arrayref(r, i, st) ↔ exactreftype(refval(r), mkarraytype(ty), st) ∧ r -- _length ∈ st ∧ st[r -- _length] = intval(i) ∧ is_arrayref(r, i, st)

And obtained the following new goals

Proof step 6:
⊦ r ≠ jvmref → (r ∈ addclass(class1, fis, st) ↔ r ∈ st)
Proof step 7:
r ≠ jvmref ⊦ (addclass(class1, fis, st)[r -- sk]) = st[r -- sk]
Proof step 10:
⊦ r = jvmref, r ∈ st ∧ r -- _type ∈ addclass(class0, fis, st) ∧ is_typevalue(st[r -- _type]) ∧ st[r -- _type] .type = mkarraytype(ty) ∧ r -- _length ∈ addclass(class0, fis, st) ∧ st[r -- _length] = intval(i) ∧ is_arrayref(r, i, st) ↔ exactreftype(refval(r), mkarraytype(ty), st) ∧ r -- _length ∈ st ∧ st[r -- _length] = intval(i) ∧ is_arrayref(r, i, st)
