Proof step 6 from proof validrefvalnotnull-addobj (conclusion)

⊦ newref(r1, st) ∧ validrefvalnotnull(str, val, ty1, st) → validrefvalnotnull(str, val, ty1, addobj(r1, class, fis, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
newref(r1, st), validrefvalnotnull(str, val, ty1, st) ⊦ r1 = jvmref, validrefvalnotnull(str, val, ty1, addobj(r1, class, fis, st))

Rule argument
