The spec for java.beans.BeanProperty.(expert, required, visual update): http://download.java.net/jdk9/docs/api/java/beans/BeanProperty.html asserts that: expert(): "Returns:true if the annotated property is an expert property; false otherwise." required(): "Returns:true if the annotated property is a required property; false otherwise." visualUpdate(): "Returns: true if the corresponding component is repainted; false otherwise." but they returns null instead of boolean value. Please see the details in the attached Test.java Due to this issue the following JCK tests fail: api/java_beans/BeanProperty/index.html#BeanProperty[test_expertFalse] api/java_beans/BeanProperty/index.html#BeanProperty[test_requiredFalse] api/java_beans/BeanProperty/index.html#BeanProperty[test_requiredTrue] api/java_beans/BeanProperty/index.html#BeanProperty[test_visualUpdateFalse]
