> When throwing HttpResponseException, it does not dispose the underlying entity. This can cause conn pool to be stuck, imagine a normal retry loop using the same HttpClient. Perhaps it should be wrapped inside #handleResponse.
> {code:java}
> public void saveContent(final File file) throws IOException {
> assertNotConsumed();
> final int status = response.getCode();
> if (status >= HttpStatus.SC_REDIRECTION) {
> throw new HttpResponseException(status, response.getReasonPhrase());
> }
> try (FileOutputStream out = new FileOutputStream(file)) {
> final HttpEntity entity = this.response.getEntity();
> if (entity != null) {
> entity.writeTo(out);
> }
> } finally {
> this.consumed = true;
> }

> {code}
> An alternative may be calling response.close(), which its behavior is documented here. I'm not sure how to check the "if supported" part though.
