2002-03-24  Eric Blake  <ebb9@email.byu.edu>

        * java/beans/IntrospectionException.java: Update to 1.4.
        * java/beans/PropertyVetoException.java: Ditto.

2002-03-24  Eric Blake  <ebb9@email.byu.edu>

        * gnu/java/beans/BeanInfoEmbryo.java (hasMethod): Use
        Arrays.equals instead of ArrayHelper.equalsArray.

2002-03-24  C. Brian Jones <cbj@gnu.org>

        * java/beans/Introspector.java: added new static final fields
        introduced in 1.2, lots of other updates remain to be done

2002-03-24  C. Brian Jones <cbj@gnu.org>

        * java/beans/Introspector.java: reformatting

2002-03-24  C. Brian Jones <cbj@gnu.org>

        * java/beans/Introspector.java: default beanInfoSearchPath will
        not include sun.beans.infos given we provide no such package and
        the API doesn't really require it; gnu.java.beans.info is the
        default.

2002-03-24  Mark Wielaard  <mark@klomp.org>

        Thanks to Orp developers
        * gnu/java/beans/editors/NativeBooleanEditor.java (setAsText(String)):
        switch TRUE and FALSE return values.
