Proof step 5 from proof validstatfields-throw-predef (previous step)

_mode .ref = jvmref ∧ ¬ _mode .key ∈ sks ∧ ( ¬ is_fskey(_mode .key) ∨ _mode .key .fs .type ≠ void_type ∨ _mode .key .fs .field ≠ `initstate' .field ∧ _mode .key .fs ≠ mkfs(`java.lang.Object' .class, void_type, `uninit' .field)), validstatfields(str, sks, st), is_predefined_class(class), newref(r, st) ⊦ r = jvmref, validstatfields(str, sks, addobj(r, class, [], st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
validstatfields(str, sks, st), is_predefined_class(class), newref(r, st) ⊦ r = jvmref, validstatfields(str, sks, addobj(r, class, [], st)), mkfs(`java.lang.Object' .class, void_type, `mode' .field) ' ∈ sks
