According to the specification for BlockingQueue.drainTo(Collection c, int maxElements), this method should return "the number of elements transferred". However the implementation of this method for LinkedBlockingQueue and LinkedBlockingDeque when given a negative number returns the given negative number.
Invoking drainTo(Collection, int) with a value of 0 or less should simply return 0.
This change has been pulled from Doug Lea's CVS and I have already reviewed it. Sending to the list for further scrutiny/review.
