Hi, http://cr.openjdk.java.net/~psandoz/tl/JDK-8024405-spliterators-size-concurrent/webrev/
This fixes an oversight in creating spliterators from the iterator of a collection or directly from an iterator (+ primitive variants). If CONCURRENT is supplied as a characteristic then the returned spliterator should not report SIZED/SUBSIZED. This could have resulted in an issue with ArrayBlockingQueue since it's spliterator is created from a weakly consistently iterator and thus exact size is not known. A CCC is required. Paul.
