Proof step 12 from proof isarray-put-samefield (previous step)

oktype(val, ty, st), r ≠ jvmref ∧ r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ∧ is_arraytype(st[r -- _type] .type) ∧ okarray(r, st[r -- _type] .type .type, st) ⊦ mkfs(class, ty, fieldvar) ' = _type, mkfs(class, ty, fieldvar) ' = _length, is_array(r, st[r -- mkfs(class, ty, fieldvar) ', val])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ okarray(r, ty, st) → r ≠ jvmref ∧ r ∈ st
Proof step 11:
oktype(val, ty, st), r -- _type ∈ st, is_typevalue(st[r -- _type]), is_arraytype(st[r -- _type] .type), okarray(r, st[r -- _type] .type .type, st), r ∈ st ⊦ mkfs(class, ty, fieldvar) ' = _type, mkfs(class, ty, fieldvar) ' = _length, r = jvmref, is_array(r, st[r -- mkfs(class, ty, fieldvar) ', val])
