I had a strange behaviour of httpclient-3.1: When using

when i just called getResponseBodyAsString() before getting the same
again as stream (or just called getResponseBodyAsString).
Another class (written to try this https-request with httpclient) which
does essentially the same (only with hard-coded params like host,
credentials and so on, the class that actually is used is more generic)
had no problems with calling the stream-returning-method.
Can someone figure that out? I'm completely clueless ;)
There is nothing strange about this behaviour.
HttpMethod#releaseConnection makes sure the response content is fully
consumed prior to releasing the connection back to the pool and closes
the InputStream in order to prevent possible corruption of the
underlying connection.
HttpMethod#getResponseBodyAsString method behaves differently because
it creates an in-memory copy of the response body.
Consider upgrading to HttpClient 4.0.

So, if I got that right, calling getResponseBodyAsString() first works
because after that call, the response body is cached locally and
getResponseBodyAsStream() uses that cached response?
Yes, that is the case.
Are there any major changes from 3.1 to 4.0 (affecting my code)? Because
my time to work on this project is running out rather quickly. :(
That depends entirely on your code. You should seriously consider
upgrading because HttpClient 3.1 is pretty much end of life.
