<Beans Dev> Regression in Introspector

[Vadim Beilin]

Hello
We have come across what looks like a regression between Java 8 and Java 9.

The following program prints different results.
------------------------------ BeansMain.java
import java.beans.*;

class Parent<T> {
    T value;
    public T getValue() {
        return value;
    }
    protected void setValue(T value) {
        this.value = value;
    }
}

class Child extends Parent<Runnable> {
    @Override
    public void setValue(Runnable value) {
        super.setValue(value);
    }
}

public class BeansMain {
    public static void main(String[] args) throws IntrospectionException {
        BeanInfo beanInfo = Introspector.getBeanInfo(Child.class);
        for (PropertyDescriptor pd : beanInfo.getPropertyDescriptors()) {
            System.out.println(pd.getName() + "\n  >> " +
pd.getReadMethod() + "\n  << " + pd.getWriteMethod());
        }
    }
}
------------------------------

With Java 8 (1.8.0_161-b12):
------------------------------
class
  >> public final native java.lang.Class java.lang.Object.getClass()
  << null
value
  >> public java.lang.Object Parent.getValue()
  << public void Child.setValue(java.lang.Runnable)
------------------------------

With Java 9 (9.0.1+11):
------------------------------
class
  >> public final native java.lang.Class java.lang.Object.getClass()
  << null
value
  >> public java.lang.Object Parent.getValue()
  << null
------------------------------

Is it something you have seen before? Does it look like a bug to you?



Thanks,
Vadim
