RFR(s): 8166446 SingletonIterator.forEachRemaining doesn't advance before calling action

[Stuart Marks]

Hi all,

Please review this small fix to adjust the behavior of 
SingletonIterator.forEachRemaining in the case where its action throws an exception:

     http://cr.openjdk.java.net/~smarks/reviews/8166446/webrev.0/

Strictly speaking, this behavior is undefined (see the spec adjustment 
JDK-8168745 [1] [2] that Paul Sandoz pushed recently). However, we felt it was 
reasonable to make this case behave consistently with the default implementation 
of Iterator.forEachRemaining(), which advances before calling the action.

Also, please ignore the extra changeset comment lines in the webrev. There's 
only one changeset here:

     rev 16204 : 8166446: SingletonIterator.forEachRemaining doesn't advance 
before calling action

Something funny is up with webrev....

Thanks,

s'marks
