[jira] [Created] (HTTPCLIENT-2003) DefaultHostnameVerifier.verify failled for host not ending with public suffix

JANTON created HTTPCLIENT-2003:
----------------------------------

             Summary: DefaultHostnameVerifier.verify failled for host not ending with public suffix
                 Key: HTTPCLIENT-2003
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2003
             Project: HttpComponents HttpClient
          Issue Type: Bug
    Affects Versions: 4.5.9
            Reporter: JANTON


Hello,

The following use case *doesn't* work anymore with HttpClient *_4.5.9_* on DefaultHostnameVerifier (was ok with version _4.5.8_) :

_DefaultHostnameVerifier.verify(String, X509Certificate)_ return *+true+* when called with :
 # a _host_ like "_a.b.c_"
 # and a _certificate_ like "_CN=*.b.c_"
 # and a _publicSuffixMatcher_ that +doesn't+ contain "_b.c_".

This could be highlighted by adding the flowing lines to _org.apache.http.conn.ssl.TestDefaultHostnameVerifier#testIdentityMatching()_ :
{code:java|title=org.apache.http.conn.ssl.TestDefaultHostnameVerifier#testIdentityMatching()}
Assert.assertTrue(DefaultHostnameVerifier.matchIdentity("a.b.c", "*.b.c", publicSuffixMatcher));
Assert.assertTrue(DefaultHostnameVerifier.matchIdentityStrict("a.b.c", "*.b.c", publicSuffixMatcher));
{code}

This change was introduced by HTTPCLIENT-1991. For me, it looks like an unintentional side effect. Could you please have a look.

Thank you very much for this great library.

Best regards
