Description

The CompositeReadableBuffer allows aggregating incoming byte[] data (e.g delivery frame contents) to be used by other areas. If a CRB reads to the end of its existing content array(s) and is then further expanded with more data as it becomes ready, the new content can't be read and instead an IOOBE occurs.
