Proof step 3 from proof validfield-put-statfield-01 (previous step)

rk = r0 -- sk, r0 = jvmref, r ≠ jvmref ∨ sk ≠ sk0 ⊦ validfield(str, r, sk0, st[rk, val]) ↔ validfield(str, r, sk0, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
r ≠ jvmref ∨ sk ≠ sk0 ⊦ validfield(str, r, sk0, st[jvmref -- sk, val]) ↔ validfield(str, r, sk0, st)
