Proof step 5 from proof is_obj-addobj-01 (previous step)

fis .keys = instfields(class), validfieldinits(fis, st), class+∃(str, class) ⊦ r = jvmref, is_abstract(class), class+∃(str, (addobj(r, class, fis, st)[r -- _type]) .type .class) ∧ ¬ is_abstract((addobj(r, class, fis, st)[r -- _type]) .type .class) ∧ is_obj(r, addobj(r, class, fis, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ fis .keys = instfields(class) → ¬ _type ∈ fis
Proof step 3:
¬ _type ∈ fis ⊦ (addobj(r, class1, fis, st)[r -- _type]) = typeval(mkclasstype(class1))
Proof step 4:
⊦ fis .keys = instfields(class) ∧ validfieldinits(fis, st) ∧ r ≠ jvmref → is_obj(r, addobj(r, class, fis, st))
