Proof step 815 from proof hasSharing-put-index-refval (previous step)

st[r0 -- _type] .type = mkarraytype(ty), is_arraytype(st[r0 -- _type] .type), validref(str, r2, ty, st), disjoint(str, r ' + r2 ', st), hasSharing(r, st[r0 -- i ', refval(r2)]), r2 = jvmref → is_reftype(ty) ⊦ r = r2, r0 = jvmref, hasSharing(r, st), hasSharing(r2, st), junkref(str, r, st)

And obtained the following new goals

Proof step 814:
st[r0 -- _type] .type = mkarraytype(ty), hasSharing(r, st[r0 -- i ', refval(r2)]), disjoint(str, r ' + r2 ', st), validref(str, r2, ty, st), r2 = jvmref → is_reftype(ty) ⊦ r0 = jvmref, r = r2, junkref(str, r, st), hasSharing(r2, st), hasSharing(r, st)
