One trick I use quite a lot is ReflectionToStringBuilder from Apache
commons, then compare the strings:

http://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/la=
ng3/builder/ReflectionToStringBuilder.html

Use the SHORT_PREFIX_STYLE:

http://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/la=
ng3/builder/ToStringStyle.html#SHORT_PREFIX_STYLE

Have fun,

Matthew Farwell.
