Proof step 11 from proof junkref-addarray-newref-put (previous step)

refs = r + refs1, newref(r0, st), is_bytelist(vals), junkrefs (str, refs, (addarray(r0, byte_type, vals, st)[r -- _type]) .type, addarray(r0, byte_type, vals, st)[r1 -- mkfs(class, mkarraytype(byte_type), fieldvar) ', refval(r0)]) ⊦ r0 = jvmref, refs = [], ∃ refs0. refs0 ≠ [] ∧ refs0 .first = r ∧ junkrefs(str, refs0, st[refs0 .first -- _type] .type, st)

Proof step 10:
newref(r0, st), is_bytelist(vals), junkrefs (str, r ' + refs1, (addarray(r0, byte_type, vals, st)[r -- _type]) .type, addarray(r0, byte_type, vals, st)[r1 -- mkfs(class, mkarraytype(byte_type), fieldvar) ', refval(r0)]) ⊦ r0 = jvmref, ∃ refs0. refs0 ≠ [] ∧ refs0 .first = r ∧ junkrefs(str, refs0, st[refs0 .first -- _type] .type, st)
