Proof step 13 from proof junkref-put-other-fieldclass (previous step)

is_arraytype(st[r0 -- _type] .type), junkref(str, r, st[r0 -- fs ', val]), path∃(str, r, r0, st) ⊦ r0 = jvmref, fs ' = _type, junkref(str, r, st), contains(str, st[r -- _type] .type, fs)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 9:
⊦ ¬ junkref(str, r, st) ∧ fs ' ≠ _type ∧ is_arraytype(st[r0 -- _type] .type) ∧ fs ' ≠ _length → ¬ junkref(str, r, st[r0 -- fs ', val])
Proof step 12:
¬ (¬ junkref(str, r, st) ∧ fs ' ≠ _type ∧ is_arraytype(st[r0 -- _type] .type) ∧ fs ' ≠ _length), is_arraytype(st[r0 -- _type] .type), junkref(str, r, st[r0 -- fs ', val]), path∃(str, r, r0, st) ⊦ r0 = jvmref, fs ' = _type, junkref(str, r, st), contains(str, st[r -- _type] .type, fs)
