> When OData V4 batch request payload is more than 4MB, the payload parsing gets stuck in deadlock. Both PipedOutputStream and PipedInputStream goes into lock there waiting indefinitely. 
> The buffer which is used as a circular buffer has a size of 4MB initialised in PipedInputStream. Whenever the batch request payload is greater than 4MB, both the main thread & future task goes into deadlock. Attached both the lock waiting threads.
