Proof step 18 from proof validrefkeynotnull-addarray (conclusion)

⊦ newref(r1, st) ∧ validrefkeynotnull(str, rk, ty1, st) → validrefkeynotnull(str, rk, ty1, addarray(r1, ty, vals, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 17:
newref(r1, st), validrefkeynotnull(str, rk, ty1, st) ⊦ r1 = jvmref, validrefkeynotnull(str, rk, ty1, addarray(r1, ty, vals, st))

Rule argument

[emptyarg]
