> There is a bug in HttpResponse::readChunkedContent that prevents it to stop reading content
when it exceeds the maximum allowed size.
> There [is a variable contentBytesRead|https://github.com/apache/nutch/blob/master/src/plugin/protocol-http/src/java/org/apache/nutch/protocol/http/HttpResponse.java#L404]
that is used to check how much content has been read, but it is never updated, so it always
stays null, and [the size check|https://github.com/apache/nutch/blob/master/src/plugin/protocol-http/src/java/org/apache/nutch/protocol/http/HttpResponse.java#L440-L442]
always returns false (unless a single chunk is larger than the maximum allowed content size).
> This allows any server to cause out-of-memory errors on our size.
