Proof step 9 from proof compatobj-mode (previous step)

⊦ r = jvmref, is_classtype((st[_mode, val][r -- _type]) .type) ∧ class+∃(str, (st[_mode, val][r -- _type]) .type .class) ∧ compatfields(str, r, instfields((st[_mode, val][r -- _type]) .type .class), st[_mode, val]) ↔ compatobj(str, r, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 8:
⊦ r = jvmref, is_classtype(st[r -- _type] .type) ∧ class+∃(str, st[r -- _type] .type .class) ∧ compatfields(str, r, instfields(st[r -- _type] .type .class), st[_mode, val]) ↔ compatobj(str, r, st)
