RFR(S): 8240854: [REDO] some jaotc failures of fastdebug build with specific flags

[Vladimir Ivanov]

src/hotspot/share/opto/subtypenode.cpp:

+  // Oop can't be a subtype of abstract type that has no subclass.
+  if (sub_t->isa_oopptr() && superk->is_instance_klass() &&
+      !superk->is_interface() && superk->is_abstract() &&
+      !superk->as_instance_klass()->has_subklass()) {
+    return TypeInt::CC_GT;
+  }

Why don't you register the dependency anymore (assert_leaf_type(superk))?

Best regards,
Vladimir Ivanov
