Javadoc Example for EqualsBuilder is questionable
-------------------------------------------------

                 Key: LANG-353
                 URL: https://issues.apache.org/jira/browse/LANG-353
             Project: Commons Lang
          Issue Type: Bug
            Reporter: Christoph Kutzinski
            Priority: Minor


The Javadoc example for the class EqualsBuilder ist questionable:

 public boolean equals(Object obj) {
   if (obj instanceof MyClass == false) {
     return false;
   }
  ...

The implementation with instanceof lacks guarantees like equals-symmetry  (see 
e.g. http://www.agiledeveloper.com/articles/equals062002.htm  for a discussion 
of the issue)
The example should be changed to use getClass(). Attention: the solution in the 
link above is incomplete as it doesn't check for null
