Description

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.
