And obtained the following new goals

Proof step 5:
⊦ newref(r, st) ↔ r ≠ jvmref ∧ (∀ rk. rk ∈ st → rk .ref ≠ r)
Proof step 26:
r < r0, jvmref < r, jvmref < r0, r0 < r1, r < r1, jvmref < r1, r1 < r2, r0 < r2, r < r2, jvmref < r2, r2 < r3, r1 < r3, r0 < r3, r < r3, jvmref < r3, ∀ r. ∃ r0. r < r0, ∀ r0. r0 ∈ st → r0 < r ⊦ r1 = r2, r0 = r2, r0 = r1, r = r2, r = r1, r = r0, r2 = jvmref, r = jvmref, (r2 -- sk ∈ st → r4 ≠ r2) ∧ r1 ≠ jvmref ∧ (∀ rk. rk ∈ st → rk .ref ≠ r1) ∧ newref(r0, st) ∧ (r -- sk0 ∈ st → r5 ≠ r)
