Name: nt126004 Date: 02/06/2002 FULL PRODUCT VERSION : java version "1.4.0-rc" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-rc-b91) Java HotSpot(TM) Server VM (build 1.4.0-rc-b91, mixed mode) FULL OPERATING SYSTEM VERSION : SunOS savoir 5.8 Generic_108528-12 sun4u sparc SUNW,Ultra-5_10 A DESCRIPTION OF THE PROBLEM : There are a number of classes that do not respect the implied contract for equals and hashCode. See, for example, Joshua Bloch's book "Effective Java", items 7-8. ava.awt.font.GlyphVector defines equals(java.awt.font.GlyphVector) but doesn't redefine equals(Object) java.awt.geom.Area defines equals(java.awt.geom.Area) but doesn't redefine equals(Object) org.apache.xpath.objects.XObject defines equals(org.apache.xpath.objects.XObject) but doesn't redefine equals(Object) sun.security.krb5.Realm defines equals(sun.security.krb5.Realm) but doesn't redefine equals(Object) sun.security.krb5.internal.HostAddresses defines equals(sun.security.krb5.internal.HostAddresses) but doesn't redefine equals(Object) sun.security.krb5.internal.KerberosTime defines equals(sun.security.krb5.internal.KerberosTime) but doesn't redefine equals(Object) com.sun.corba.se.internal.core.ORBVersionImpl redefines equals(Object) but not hashCode() com.sun.corba.se.internal.ior.AlternateIIOPAddressCo mponent redefines equals(Object) but not hashCode() com.sun.corba.se.internal.ior.CodeSetsComponent redefines equals(Object) but not hashCode() com.sun.corba.se.internal.ior.GenericIdEncapsulation redefines equals(Object) but not hashCode() com.sun.corba.se.internal.ior.IIOPAddressBase redefines equals(Object) but not hashCode() com.sun.corba.se.internal.ior.IIOPProfile redefines equals(Object) but not hashCode() com.sun.corba.se.internal.ior.JavaCodebaseCompone nt redefines equals(Object) but not hashCode() com.sun.corba.se.internal.ior.ORBTypeComponent redefines equals(Object) but not hashCode() com.sun.corba.se.internal.ior.ObjectId redefines equals(Object) but not hashCode() com.sun.corba.se.internal.ior.ObjectKey redefines equals(Object) but not hashCode() com.sun.corba.se.internal.ior.ObjectKeyTemplateBase redefines equals(Object) but not hashCode() com.sun.corba.se.internal.ior.OldPOAObjectKeyTempl ate redefines equals(Object) but not hashCode() com.sun.corba.se.internal.ior.POAIdBase redefines equals(Object) but not hashCode() com.sun.corba.se.internal.ior.POAObjectKeyTemplate redefines equals(Object) but not hashCode() com.sun.corba.se.internal.ior.WireObjectKeyTemplate redefines equals(Object) but not hashCode() com.sun.corba.se.internal.orbutil.RepIdDelegator redefines equals(Object) but not hashCode() com.sun.corba.se.internal.orbutil.RepIdDelegator_1_3 redefines equals(Object) but not hashCode() com.sun.corba.se.internal.orbutil.RepIdDelegator_1_3 _1 redefines equals(Object) but not hashCode() java.awt.Font$FontLineMetrics redefines equals(Object) but not hashCode() java.beans.IndexedPropertyDescriptor redefines equals(Object) but not hashCode() java.beans.PropertyDescriptor redefines equals(Object) but not hashCode() java.text.CharSet redefines equals(Object) but not hashCode() javax.imageio.ImageTypeSpecifier redefines equals(Object) but not hashCode() javax.imageio.ImageTypeSpecifier$Banded redefines equals(Object) but not hashCode() javax.imageio.ImageTypeSpecifier$Interleaved redefines equals(Object) but not hashCode() javax.swing.text.SimpleAttributeSet$EmptyAttributeSet redefines equals(Object) but not hashCode() org.apache.xalan.transformer.StackGuard redefines equals(Object) but not hashCode() org.apache.xml.utils.URI redefines equals(Object) but not hashCode() org.apache.xpath.Arg redefines equals(Object) but not hashCode() sun.security.krb5.internal.rcache.a9 redefines equals(Object) but not hashCode() sun.security.x509.AVAComparator redefines equals(Object) but not hashCode() sun.security.x509.EDIPartyName redefines equals(Object) but not hashCode() sun.security.x509.GeneralName redefines equals(Object) but not hashCode() sun.security.x509.GeneralSubtree redefines equals(Object) but not hashCode() sun.security.x509.OtherName redefines equals(Object) but not hashCode() sun.security.x509.PolicyInformation redefines equals(Object) but not hashCode() com.sun.corba.se.internal.core.GIOPVersion redefines equals(Object) but not hashCode() org.apache.xml.dtm.ref.DTMNodeProxy redefines equals(Object) but not hashCode() sun.security.jgss.ProviderList$PreferencesEntry redefines equals(Object) but not hashCode() java.awt.DisplayMode defines equals(java.awt.DisplayMode) but doesn't redefine equals(Object) STEPS TO FOLLOW TO REPRODUCE THE PROBLEM : 1. Problems found by applying automatic tools to JDK libraries. However, manual inspectation of the classes reveals the same problems.
