This patch replaces the use of Class::getPackage with
Class::getPackageName in jdk.internal.reflect.ReflectionFactory,
sun.util.resources.BreakIteratorResourceBundle, and
javax.xml.catalog.CatalogMessages. Class::getPackageName avoids the
overhead of constructing Package objects.

ReflectionFactory::packageEquals does not specify if the Class object is
an array class. In the current implementation it returns true even if
the input parameters are both array classes but in two different runtime
package. I added an assert instead of retaining the current behavior.
