Description

When accessing the SimpleWebdavServlet with the "root" path, that is the same path as set with the resource-path-prefix, a NullPointerException is thrown:

The problem seems to be that the ResourceFactoryImpl.createResource method (or rather the getNode method) is not prepared to a DavResourceLocator instance whose resourcePath is null.

I could imagine, that the ResourceFactoryImpl.getNode() method might want to return the root node in this case ?
