For anyone else:

I got a NullpoingterException in at VFS.getChild() when starting JBoss (sadly lost the stacktrace)

This was due to that I was importing spring resources from a folder that didn't exist (using a wildcard as in folder/*.xml)

In org.jboss.spring.vfs.VFSResourcePatternResolvingHelper#locateResources

        if (!oneMatchingRootOnly)
        {
            while (urls.hasMoreElements())
                resources.addAll(getVFSResources(urls.nextElement(), subPattern, pathMatcher));
        } else
        {
            resources.addAll(getVFSResources(classLoader.getResource(rootDirPath), subPattern, pathMatcher));
        }
        return resources.toArray(new Resource[resources.size()]);


This getVFSResources(urls.nextElement(), subPattern, pathMatcher) returned null which later through the exception when accessing the URL
