Although this issue has been reported in the past through https://issues.apache.org/jira/browse/HTTPCLIENT-1699 , it is not yet fixed.
I have previously reported it under https://issues.apache.org/jira/browse/HTTPCLIENT-1869 and was requested to provide more details

In the attached log, the issue occurs on second request.
Removing Deflate from Accept-Encoding is a workaround, so issue is located in Deflate management, GZIP works fine.
