Proof step 6 from proof addobj-throw-subset (previous step)

st[_mode] = noval, newref(r, st) ⊦ r = jvmref, st ⊆ addobj(r, class, fis, st) ∧ ¬ _mode ∈ st ∨ _mode × noval ∈ st ∧ st -- _mode ⊆ addobj(r, class, fis, st) -- _mode

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ newref(r, st) → (st ⊆ addobj(r, class1, fis, st0) ↔ st ⊆ st0)
Proof step 5:
st[_mode] = noval, newref(r, st), _mode ∈ st ⊦ r = jvmref, st -- _mode ⊆ addobj(r, class, fis, st) -- _mode
