resourcePaths returns null

Hi,
Suddenly a few days ago (unclear exactly when) when i run the code below it returns null. It worked two weeks ago and still works if I step back to version 2.0-beta-1.
I'm running the goal "tomcat7:run"

code that returns null:
getServletContext().getResourcePaths(path);

pom config:
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<!-- <version>2.0-beta-1</version> -->
<version>2.0-SNAPSHOT</version>
