…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. Now the HTTP client reads large data by chunks, therefore the amount of consumed memory is proportional to the amount of sent 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.
