Hi Mendix Community. I need to integrate my Mendix with a WebDAV server. I found a nice library online called Sardine that does exactly what I want. When I use the library in a standalone java project it work amazingly. However trying to use this inside my Mendix application is proving difficult. When trying to run a simple function I get: (I also tried using the Apache Jackrabbit library with the same error) Uncaught fatal error from thread [MxRuntimeSystem-akka.actor.action-dispatcher-13] shutting down ActorSystem [MxRuntimeSystem] java.lang.ExceptionInInitializerError: null at com.github.sardine.impl.SardineImpl.list(SardineImpl.java:354) at
