Tom White updated HADOOP-1294:
------------------------------
Attachment: java6_unchecked.patch
This is occurring because the getConstructor method on Class changed between Java 5 and 6, from:
public Constructor<T> getConstructor(Class... parameterTypes)
to
public Constructor<T> getConstructor(Class<?>... parameterTypes)
This patch should fix the warning. I haven't managed to test it on Java 6 - Tahir, would you be able to try it please?

Thanks Tahir. I've now got Java 6 working which exposed a few more warnings. This patch fixes them. I've checked it with Java 5 too.
