Proof step 6 from proof validref-nopath-superset (previous step)

¬ newref(r, st0), validrefnotnull(str, r, st[r -- _type] .type, st), st ⊆ st0, newref(r, st), is_valid_ref(str, r, st0) ⊦ r = jvmref

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
is_valid_ref(str, r, st0), newref(r, st), st ⊆ st0, validrefnotnull(str, r, st[r -- _type] .type, st) ⊦ r = jvmref, newref(r, st0)
