Java SDK: ClassCastException when casting to javax.net.ssl.HttpsURLConnection in SFOAuthService

Using the ShareFile Java SDK 3.1.5 I get a ClassCasstException in SFOAuthService:authenticate on the following line: 
connection = (HttpsURLConnection)SFConnectionManager.openConnection(e)
I assume it occurs because it expects a javax.net.ssl.HttpsURLConnection, but as we use weblogic the openConnection(e)-call returns a weblogic.net.http.HttpsURLConnection, which cannot be cast to javax.net.ssl.HttpsURLConnection. Both classes extends java.net.HttpURLConnection.

Telling weblogic to use the Sun Http-handler by adding the line below works, but it is not a preferable option as our system has multiple Http-integrations.
set JAVA_OPTIONS=%JAVA_OPTIONS% -DUseSunHttpHandler=true
Another option seems to be replacing the SFOAuthService-class with my own implementation that casts to weblogic.net.http.HttpsURLConnection or simply a java.net.HttpURLConnection, but do anyone have any other suggestions?

@Øystein Molnes   Currently there is no other option than to do the explicit casting. Going forward SFConnectionManager  will be depreacated and replaced it with a connection factory which deals with a generic interface IHttpsConnection allowing us to switch between okhttp, HttpsUrlConnection etc. But there is no formal timeline to release this to public SDK yet.
