Proof step 17 from proof junkref-put-field (conclusion)

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

And obtained the following new goals

Proof step 16:
fs ' ∈ instfields(st[r -- _type] .type .class), st[r0 -- _type] .type ≤ fs .type, is_obj(r, st), junkref(str, r, st[r -- fs ', refval(r0)]) ⊦ r0 = jvmref, junkref(str, r0, st), junkref(str, r, st)
