When creating new file in Modeshape repository (configured to use Filesystem connector) using a WebDav client, there is a RepositorySourceException thrown. I tried WebDav methods provided in Jackrabbit Webdav package and also WebDav methods from Sardine framework, both resulted in org.modeshape.graph.connector.RepositorySourceException: Attempt to set or update invalid property names: [jcr:encoding]

Here is a code snippet which uses PutMethod class from Jackrabbits's WebDav package:

try {
DavMethodBase put = new PutMethod("http://127.0.0.1:8080/modeshape-webdav/file6.txt");
initClient().executeMethod(put);

System.out
.println(put.getStatusCode() + " " + put.getStatusText());

} catch (Exception e)
{
System.out.println(e.getCause());
e.printStackTrace();
}

and here's a stacktrace SOA-P's console:
