FULL PRODUCT VERSION :
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-b21)
Java HotSpot(TM) Client VM (build 1.4.1-b21, mixed mode)


FULL OPERATING SYSTEM VERSION :

n/a

ADDITIONAL OPERATING SYSTEMS :
only observed this on Linux, could not reproduce on Solaris.

A DESCRIPTION OF THE PROBLEM :
javac generates deprecated warnings when a class implements
a deprecated method from an ancestor class or interface.

Deprecation warnings should not be generated for methods that
are themselves declared "@deprecated" either simply because
the implement the method or because they call deprecated methods.

This looks very similar to bug 4750187.

EXPECTED VERSUS ACTUAL BEHAVIOR :

The provided will generate a deprecated warning while
compiling bar with javac because bar implements useless().

If a method implementation itself includes a @deprecated
directive, then the compiler should omit the deprecated
warning. Doing so makes the deprecated warnings more relevant.


STEPS TO REPRODUCE THE PROBLEM :
javac -deprecation deprecated.java
rm two/bar.class
javac -deprecation deprecated.java

ERROR MESSAGES/STACK TRACES THAT OCCUR :
javac -deprecation deprecated.java
./two/bar.java:21: warning: useless() in one.foo has been deprecated
  public foo useless() {
             ^
1 warning


REPRODUCIBILITY :
This bug can be reproduced always.
