Apart from the documentation I would add two things that you can see

Hi devs,
I've just realized that using @override is enough to generate a proper javadoc copied
from the overriden method and that checkstyle doesn't complain either.
Basically instead of writing:
/**
* {@inheritDoc}
*
* @see org.xwiki.logging.LoggerManager#popLogListener()
*/
@Override
public EventListener popLogListener()
We can simply write:
@Override
public EventListener popLogListener()
Advantages:
1) Less text to type and smaller class files
2) Less duplicated text
I thus propose to use this from now and to progressively remove unnecessary javadoc in
our legacy code.
BTW this is also explained in the javadoc tool:
See section "Automatic Reuse of Method Comments" in
http://download.oracle.com/javase/1.3/docs/tooldocs/win32/javadoc.html
WDYT?
Here's my +1
ok in case you're wondering if using @override is valid when implementing an
interface, here's a little detective work:
1) If you read Java 6 javadoc you'll find in
http://download.oracle.com/javase/6/docs/api/java/lang/Override.html:
"Indicates that a method declaration is intended to override a method declaration in
a superclass. If a method is annotated with this annotation type but does not override a
superclass method, compilers are required to generate an error message."
So this seems to indicate it's not valid. However…
2) If your read http://blogs.oracle.com/ahe/entry/override_snafu you'll find that the
javadoc for 1.6 isn't correct (read also
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5008260) and reading
http://stackoverflow.com/questions/212614/should-a-method-that-implements-a…
will show you that actually using @override is supported when implementing an interface in
Java 6 but not in Java 5… ;)
