Proof step 7 from proof validrefnotnull-put-statfield-01 (conclusion)

⊦ rk1 .ref = jvmref ∧ r ≠ jvmref ∧ ¬ validrefnotnull(str, r, ty1, st[rk1, val]) → ¬ validrefnotnull(str, r, ty1, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ validrefnotnull(str, r, ty, st) → r ≠ jvmref
Proof step 6:
rk1 .ref = jvmref, validrefnotnull(str, r, ty1, st) ⊦ validrefnotnull(str, r, ty1, st[rk1, val])

Rule argument
