Proof step 35 from proof isobj-addobj-04 (previous step)

fis .keys = instfields(class), validfieldinits(fis, st) ⊦ r = jvmref, r ≠ jvmref ∧ (r -- _type) × typeval(mkclasstype(class)) ∈ addobj(r, class, fis, st) ∧ goodfieldsandtypes(r, instfields(class), addobj(r, class, fis, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
⊦ fis .keys = instfields(class) → ¬ _type ∈ fis
Proof step 7:
¬ _type ∈ fis ⊦ (r -- _type) × typeval(mkclasstype(class1)) ∈ addobj(r, class1, fis, st)
Proof step 34:
fis .keys = instfields(class), validfieldinits(fis, st) ⊦ r = jvmref, goodfieldsandtypes(r, instfields(class), addobj(r, class, fis, st))
