Motivation: It is hard for end-user to understand why the hostname validation failed. Let's try to help them by including the SubjectAlternativeNames if there are any. Modifications: - Wrap the X509ExtendedTrustManager and so be able to catch the CertificateException and add more details if needed - Add unit test Result: Easier to debug hostname validation problems
