Gary Gregory commented on HTTPCLIENT-1903:
------------------------------------------

I'm thinking of creating a {{HostnameVerifierFactory}} class that would provide 
the an impl with naming support if it is absent. This would mean leaving 
{{DefaultHostnameVerifierFactory}} as is for compatiblity and creatiing two new 
classes that would break up {{DefaultHostnameVerifierFactory}}.

> DefaultHostnameVerifier crashes on Android due to inexistent javax.naming 
> classes

>             Project: HttpComponents HttpClient
>          Issue Type: Bug
>    Affects Versions: 4.5.5
>            Reporter: Michael Pujos
>            Priority: Minor
>
> I'm using HttpClient on Android, repackaged to avoid conficting with the 
> platform's org.apache old packages.
> It works fine, except that making any https request will crash using the 
> defaults.
> The reason is that DefaultHostnameVerifier uses javax.naming.* classes, which 
> are not present on Android.
> So to be able to make https request, the default hostname verifier must be 
> replaced. For example:
>  
> httpClient = HttpClients.custom()
>                 .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
>                 .build();
>  
> Using NoopHostnameVerifier is rarely a good idea, so for the time being I 
> have replaced it with and older version of BrowserCompatHostnameVerifier that 
> doesn't internally call DefaultHostnameVerifier.
>  
> Ideally, I'd like DefaultHostnameVerifier to detect dynamically if 
> javax.naming.* classes are available, and switch to an alternate method not 
> using them if they are not. That way, HttpClient would work out of the box 
> for Android users.
