Proof step 10 from proof validrefnotnull-put-shortval (previous step)

is_shortvalue(st[r -- mkfs(class, short_type, fieldvar) ']), r0 ≠ jvmref ∧ validref(str, r0, ty, st) ⊦ r = jvmref, r0 = jvmref, r0 = jvmref ∨ (st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)][r0 -- _type]) .type ≤ ty ∧ ¬ junkref(str, r0, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)])

And obtained the following new goals

Proof step 9:
is_shortvalue(st[r -- mkfs(class, short_type, fieldvar) ']), validref(str, r0, ty, st) ⊦ r = jvmref, r0 = jvmref, st[r0 -- _type] .type ≤ ty ∧ ¬ junkref(str, r0, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)])
