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)

doesn't redefine equals(Object)

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()
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.
