> I'm using CXF (3.2.8 a bit old but the involved code seems always the same on master) to access the SOAP WebService WinRM on Windows Servers with the lib [WinRM4J|https://github.com/cloudsoft/winrm4j] which use the org.apache.cxf.transport.http.asyncclient.AsyncHTTPConduit.
> I saw that the underscore character is not allowed in hostname (as describe in [RFC 2396|http://www.ietf.org/rfc/rfc2396.txt]) but in the Active Directory DNS you can use underscore, so here in our private Cloud AzurePack it's possible to create a VM with an underscore in its hostname.
> When the WebService on a such VM is accessed the following exception is thrown :
> {code}

> It's not the root cause, so it's a bit difficult to find out the problem.
> The root cause is in fact an {{IllegalArgumentException: Host name may not be null}} thrown by the [HttpHost|https://github.com/apache/httpcomponents-core/blob/rel/v4.4.4/httpcore/src/main/java/org/apache/http/HttpHost.java#L80] when it's instanciated by [​CXFHttpAsyncRequestProducer#getTarget()|https://github.com/apache/cxf/blob/cxf-3.2.8/rt/transports/http-hc/src/main/java/org/apache/cxf/transport/http/asyncclient/CXFHttpAsyncRequestProducer.java#L62].
> The hostname is null because the parsing do by the java.net.URI reject the underscore (but doesn't thrown an URISyntaxException).
> I have managed a workaround (you can see it on this branch https://github.com/zerikv/cxf/commits/fix-lost-exception-hostname-with-underscore) at the end of the {{connect()}} method in the inner class {{AsyncWrappedOutputStream}} of [AsyncHTTPConduit|https://github.com/apache/cxf/blob/cxf-3.2.8/rt/transports/http-hc/src/main/java/org/apache/cxf/transport/http/asyncclient/AsyncHTTPConduit.java#L584] so that {{IllegalArgumentException}} now goes back to the user.
> It's not even the real root cause but I think it's a little better than the {{Buffer already closed for writing}} message, at least it indicates that something is wrong with the hostname.
> For my initial problem (accept the hostnames with underscore because they exist I have meet them) the only solution I can find would be to replace the URI with the URL, but I guess it's not really an option.
> If someone see another way thank for advices.
