OpenMBeanInfoSupport.equals violates parent's contract

    Description

      The class OpenMBeanInfoSupport is a subclass of MBeanInfo and overrides its equals method. In addition to the requirements of MBeanInfo.equals, it requires that its argument be an instance of OpenMBeanInfo. This means that this method violates the symmetry property guaranteed by the contract for Object.equals. If I have an object mbeanInfo of class MBeanInfo and an object openMBeanInfo of class OpenMBeanInfoSupport, then mbeanInfo.equals(openMBeanInfo) might be true while openMBeanInfo.equals(mbeanInfo) is false. Similar remarks apply to OpenMBeanAttributeInfoSupport etc.
