> Testcase org.apache.harmony.luni.tests.java.net.DatagramSocketImplTest fails to compile
on Sun or IBM java, with the error messages:

>     [javac] 	            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
>     [javac] The method setOption(int, Object) of type MockDatagramSocketImpl must override
a superclass method
>     [javac] ----------
>     [javac] 2 problems (2 errors)
> The problem is that in the Harmony implementation the getOption and setOption method
signatures are copied from the SocketOptions interface into the implementing DatagramSocketImpl
class, which is abstract.  MockDatagramSocketImpl in the testcase extends this abstract class
and annotates the methods with "@Override".  However, the method signatures must not be copied
in the reference implementations, as the "@Override" annotation throws an error saying that
the methods aren't being overridden.  
> Removing the override annotations fixes the problem, but I think the method signatures
should be removed from java.net.DatagramSocketImpl
