<Beans Dev> [9] Review Request: 8130937 Several methods in BeanProperty return null instead of boolean value

[Sergey Bylokhov]

Hello.
Please review the fix for jdk9.
Problem description:
  - The new "required" annotation was added in JDK-4058433, but this 
annotation was ignored by the PropertyDescriptor.
  - The new "expert", "hidden" annotations return null via getValue 
method, if were set to false, and this doesn't correspond to the similar 
isExpert,isHidden methods which return false. For example code below do 
not initialize the value to false, and its default value is null, but 
default value for expert is false:

-        if (info.is(PropertyInfo.Name.expert)) {
-            setValue(PropertyInfo.Name.expert.name(), Boolean.TRUE); // 
compatibility
-            setExpert(true);
-        }
