>                 Key: HTTPCLIENT-2367
>                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2367
>             Project: HttpComponents HttpClient
>          Issue Type: Bug
>          Components: HttpClient (async)
>    Affects Versions: 5.4.3, 5.4.4
>            Reporter: Jason Mathison
>            Priority: Major
>
> Starting in the 5.4.3 release of HttpClient, in the 
> org/apache/hc/client5/http/impl/async/InternalAbstractHttpAsyncClient.java 
> file, it is possible to get an Null Pointer Exception thrown by this section 
> of code:
>  
> final HttpHost resolvedTarget = target != null ? target : 
> RoutingSupport.determineHost(request);
> if (request.getScheme() == null) {
> request.setScheme(resolvedTarget.getSchemeName());
> }
>  
> The issue is that the RoutingSupport.determineHost can return null, then this 
> line
> request.setScheme(resolvedTarget.getSchemeName());
> will attempt to dereference resolvedTarget, which is null.
