Oleg Kalnichevski resolved HTTPCLIENT-1465.
-------------------------------------------

    Resolution: Not A Problem

bq. But web browser and wget works fine on that site.

So what? We do not really know if those applications simply quietly ignore the problem, do we? Likewise, one can catch EOFException exception and try to use whatever data have been received up to this point.

By the way, I also tried to use Commons Compress (which is believed to be able to handle various corner cases better) instead of the internal JRE gzip decompressor and got exactly the same result. This really seems to support my assertion that the blame here lies with the server.
