Javadoc for method
java.beans.Encoder.setPersistenceDelegate(Class type, PersistenceDelegate persistenceDelegate)
does not declare NullPointerException if the value of
persistenceDelegate parameter is null.
This behavior should be documented.

Here is example:
import java.beans.*;

public class EncoderTest02 {

    public static void main(String[] args) {
        Encoder enc = new Encoder();
        Class type = java.math.BigInteger.class;
        PersistenceDelegate persistenceDelegate = null;
        enc.setPersistenceDelegate(type, persistenceDelegate);
        System.out.println("OKAY");
    }
}
