Proof step 4 from proof junkrefs-addarray-newref-put (previous step)

junkrefs(str, refs, ty, addarray(r0, byte_type, vals, st)[r1 -- mkfs(class, mkarraytype(byte_type), fieldvar) ', refval(r0)]), newref(r0, st), is_bytelist(vals) ⊦ r0 = jvmref, junkrefs(str, refs, ty, st), is_array(r0, addarray(r0, byte_type, vals, st))

User applied rule insert rewrite lemma

And obtained the following new goals
