please review 7117612: warnings fixes in java.lang

[Stuart Marks]

Please review the following webrev submitted by Omair Majid, consisting of 
warnings fixes for a variety of files in java.lang.

http://cr.openjdk.java.net/~omajid/webrevs/warnings-day-2011/01/

It looks pretty clean, but it would be good to get another pair of eyes on this 
since there is sometimes great subtlety in java.lang.

My comments below.

AutoCloseable.java --

     java/lang/AutoCloseable.java:34: warning: [try] auto-closeable
     resource AutoCloseable has a member method close() that could
     throw InterruptedException

The warning here is kind of silly. The intent is to warn implementors of 
AutoCloseable not to throw InterruptedException. But this is an interface, not 
an implementation, and it's the AutoCloseable interface itself! We may want to 
rethink when the compiler emits this warning, instead of suppressing the 
warning in source code. Joe, what do you think about this?

CharacterName.java --

Consider narrowing the scope of @SuppressWarnings by using a local variable.

Thanks,
