Proof step 8 from proof validref-put-array-refval-03 (previous step)

val = refval(r1), is_arraytype(st[r0 -- _type] .type), validref(str, r1, st[r0 -- _type] .type .type, st), is_referencevalue(val), is_indexkey(sk), validref(str, r, ty, st), r1 = jvmref → is_reftype(st[r0 -- _type] .type .type) ⊦ r0 = jvmref, validref(str, r, ty, st[r0 -- sk, val])

And obtained the following new goals

Proof step 7:
is_arraytype(st[r0 -- _type] .type), validref(str, r1, st[r0 -- _type] .type .type, st), is_indexkey(sk), validref(str, r, ty, st), r1 = jvmref → is_reftype(st[r0 -- _type] .type .type) ⊦ r0 = jvmref, validref(str, r, ty, st[r0 -- sk, refval(r1)])
