Proof step 8 from proof validsubset-put-statfield (previous step)

r ∈ st0, junkref(str, r, st0), ∀ r, ty. validref(str, r, ty, st) → validref(str, r, ty, st0), ∀ r. ¬ r ∈ st ∧ (r = jvmref ∨ r ∈ st0) → ¬ junkref(str, r, st0[jvmref -- sk, val]) ⊦ r ∈ st

User applied rule all left

And obtained the following new goals

Proof step 7:
r ∈ st0, junkref(str, r, st0), ∀ r, ty. validref(str, r, ty, st) → validref(str, r, ty, st0), ¬ r ∈ st ∧ (r = jvmref ∨ r ∈ st0) → ¬ junkref(str, r, st0[jvmref -- sk, val]), ∀ r. ¬ r ∈ st ∧ (r = jvmref ∨ r ∈ st0) → ¬ junkref(str, r, st0[jvmref -- sk, val]) ⊦ r ∈ st
