(httpclient) RFR: 8232625: HttpClient redirect policy should be more conservative

[Daniel Fuchs]

Hi,

Please find below a fix for:

8232625: HttpClient redirect policy should be more conservative
https://bugs.openjdk.java.net/browse/JDK-8232625

webrev:
http://cr.openjdk.java.net/~dfuchs/webrev_8232625/webrev.00/

The HttpClient should only redirect codes for which the semantics
is known, and drop the request body when the request method changes.

best regards,
