Hi,

I get a Fatal Exception on runtime. The error is

This is my code:

public void test() throws Exception
{
  Sardine sardine = SardineFactory.begin("test@test.de", "test");
  List<DavResource> resources = sardine.list("https://cloud.mydomain.com/dav/Test/");

  for (DavResource res : resources)
  {
    System.out.println(res);
  }
}

My build.gradle dependencies:

implementation 'com.github.lookfirst:sardine:5.8'

Has anybody an idea, what I'm doing wrong? Please let me know if you need any information.

Thank you so much!
