It failed to invoke pcGetIDOwningClass method on an embeddable entity which has
the ID annotation. here is the exception:
java.lang.NoSuchMethodError:
com/xxx/xxx/entity/MyClass.pcGetIDOwningClass()Ljava/lang/Class;

This is because it uses different condition to add and invoke
pcNewObjectIdInstance method in PCEnhancer.
here is the section it adds pcNewObjectIdInstance in PCEnhancer.addPCMethods
if (_meta.hasAbstractPKField() == true) {
addGetIDOwningClass();
}
here is the section it invokes pcNewObjectIdInstance in
PCEnhancer.addNewObjectIdInstanceMethod
if(_meta.isEmbeddedOnly() || _meta.hasAbstractPKField() == true) {
code.aload().setThis();
code.invokevirtual().setMethod(PRE + "GetIDOwningClass",
Class.class, null);
} else {
code.classconstant().setClass(getType(_meta));
}
