Proof step 10 from proof junkref-put-refval-01 (previous step)

r0 ≠ jvmref, st[r1 -- _type] = typeval(ty0), ty0 ≤ ty, junkrefs(str, r ' + refs0, st[r -- _type] .type, st[r0 -- i ', refval(r1)]), mkarraytype(ty) ≤ st[r0 -- _type] .type, is_arraytype(st[r0 -- _type] .type) ⊦ r1 = jvmref, r0 = jvmref, mkarraytype(ty0) ≤ st[r0 -- _type] .type, junkref(str, r1, st), junkref(str, r, st)

And obtained the following new goals

Proof step 9:
st[r1 -- _type] = typeval(ty0), is_arraytype(st[r0 -- _type] .type), mkarraytype(ty) ≤ st[r0 -- _type] .type, junkrefs(str, r ' + refs0, st[r -- _type] .type, st[r0 -- i ', refval(r1)]), ty0 ≤ ty ⊦ r0 = jvmref, r1 = jvmref, junkref(str, r, st), junkref(str, r1, st), mkarraytype(ty0) ≤ st[r0 -- _type] .type
