Proof step 15 from proof getintarray-subset (previous step)

r ≠ jvmref ∧ r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ∧ is_arraytype(st[r -- _type] .type) ∧ okarray(r, st[r -- _type] .type .type, st), st ⊆ st0, r -- _length ∈ st, r ∈ st ⊦ getintarray(r, st) = getintarray(r, st0), is_arrayref(r, st[r -- _length] .intval, st)

And obtained the following new goals

Proof step 4:
⊦ st ⊆ st0 ∧ okarray(r, ty, st) → okarray(r, ty, st0)
Proof step 5:
⊦ okarray(r, ty, st) → r ≠ jvmref ∧ r ∈ st
Proof step 6:
⊦ okarray(r, ty, st) ∧ st ⊆ st0 → okarray(r, ty, st0)
Proof step 14:
r ∈ st, r -- _length ∈ st, st ⊆ st0, okarray(r, st[r -- _type] .type .type, st), is_arraytype(st[r -- _type] .type), is_typevalue(st[r -- _type]), r -- _type ∈ st ⊦ r = jvmref, getintarray(r, st) = getintarray(r, st0), is_arrayref(r, st[r -- _length] .intval, st)
