Hello,

I'm trying to deploy a simple JAX-RS app on a WildFly 10 instance but I get this error:

As far as I see, wildfly-10.0.0.Final\modules\system\layers\base\org\apache\httpcomponents\main\httpclient-4.5.jar contains the org.apache.http.conn.socket.LayeredConnectionSocketFactory class.

I've tried upgrading all the httpcomponents jars to the latest versions, but now I get another exception:

Caused by: java.lang.ClassNotFoundException: org.apache.http.protocol.HttpContext from [Module "deployment.siteaccess-backend.war:main" from Service Module Loader]

This class is present in httpcore-4.4.4.jar.

Can anybody enlighten me please?
