8 Feb 2001, eval1127@eng -- needs to be set (preserved)
in both package-private constructors (see Comments section)
----------------
java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
Java HotSpot(TM) Server VM (build 2.0fcs-E, mixed mode)

and

java version "1.4.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta-b50)
Java HotSpot(TM) Client VM (build 1.4beta-B50, mixed mode)

----------------

In the getPropertyDescriptors() method of my MyClassBeanInfo class, I set the
preferred flag for a given property.

After I retrieve the property from the BeanInfo returned from the
java.beans.Introspector.getBeanInfo( "MyClass" ); the preferred flag is not set.

In looking through the source code it is due to the package-private constructor
of FeatureDescriptor not copying the state of the preferred flag, e.g. from
java.beans.FeatureDescriptor.java line: 225 - 237

    /*
     * Package-private dup constructor
     * This must isolate the new object from any changes to the old object.
     */
    FeatureDescriptor(FeatureDescriptor old) {
expert = old.expert;
hidden = old.hidden;
name = old.name;
shortDescription = old.shortDescription;
displayName = old.displayName;
addTable(old.table);
// preferred = old.preferred; // <<<--- NEEDED
    }

This constructor should also have the following line:

preferred = old.preferred;
