> Implementations of BufferAllocator.buffer(...) are expected to throw an OutOfMemoryException if the buffer cannot be allocated. There are multiple reasons for that:
> - allocator exceeded it's memory limit
> - Netty exceeded it's direct memory limit
> - the System is unable to fulfill Netty's request for more direct memory
> For now only the first case throws an OutOfMemoryException. The second throws an OutOfDirectMemoryError, and the third an OutOfMemoryError with the "Direct buffer memory" error message.
