The signature of com.google.api.client.util.Data#nullOf is incorrect.

[GoogleCodeExporter]

The signature of om.google.api.client.util.Data#nullOf(Class) doesn't make 
sense. The existing signature is:

<T> T nullOf(Class<?> objClass);

If the return type's class should always be the same as objClass, the signature 
should be:

<T> T nullOf(Class<T> objClass);

If that isn't true, the signature should be:

Object nullOf(Class<T> objClass);

In the second case, callers can perform explicit casts as necessary. The 
current behaviour results in an implicit unchecked cast at the callsite.

The existing signature also interacts badly with the improved target-type 
inference in Java 8.
