…thonGH-119454) Reading the whole body of the HTTP response could cause OOM if the Content-Length value is too large even if the server does not send a large amount of data.

Reading the whole body of the HTTP response could cause OOM if
the Content-Length value is too large even if the server does not send
a large amount of data. Now the HTTP client reads large data by chunks,
therefore the amount of consumed memory is proportional to the amount
of sent data.
