Proof step 90 from proof maxpath-object (conclusion)

⊦ is_obj(str, r, st) ∧ st[r -- fs '] = refval(r0) ∧ fs ' ∈ instfields(st[r -- _type] .type .class) ∧ ¬ junkref(str, r, st) ∧ ¬ cyclic(str, r, st) → ¬ maxpath(str, r, st) ≤ maxpath(str, r0, st)

And obtained the following new goals

Proof step 89:
st[r -- fs '] = refval(r0), fs ' ∈ instfields(st[r -- _type] .type .class), is_obj(str, r, st), maxpath(str, r, st) ≤ maxpath(str, r0, st) ⊦ junkref(str, r, st), cyclic(str, r, st)
