Proof step 29 from proof compatobj-isobj (previous step)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 28:
compatfields(str, r, instfields(st[r -- _type] .type .class), st), class+∃(str, st[r -- _type] .type .class), is_classtype(st[r -- _type] .type) ⊦ r = jvmref, is_obj(r, st)
