Proof step 5 from proof validref-put-array-norefval (previous step)

okval(val, st[r1 -- _type] .type .type), st[r -- _type] .type ≤ ty, junkref(str, r, st[r1 -- i ', val]) ⊦ r = jvmref, is_referencevalue(val), junkref(str, r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ ¬ is_referencevalue(val) ∧ ¬ junkref(str, r, st) ∧ okval(val, st[r1 -- _type] .type .type) → ¬ junkref(str, r, st[r1 -- i ', val])

Rule argument

[crewrite-arg: junkref-put-array-norefval , F , [val, i, r1, st, r, str] → [val, i, r1, st, r, str] ]
