Buggy source:
/** 
 * Reads a batch of items from the Ringbuffer. If the number of available items after the first read item is smaller than the maxCount, these items are returned. So it could be the number of items read is smaller than the maxCount. If there are no items available, this call Reading a batch of items is likely to perform better because less overhead is involved. A filter can be provided to only select items that need to be read. If the filter is null, all items are read. If the filter is not null, only items where the filter function returns true are returned. Using filters is a good way to prevent getting items that are of no value to the receiver. This reduces the amount of IO and the number of operations being executed, and can result in a significant performance improvement.
