Henri Yandell updated LANG-353:
-------------------------------
Fix Version/s: 2.4
> 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
> Fix For: 2.4
>
>
> 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
