When trying to run a simple junit test getting the following Nullpointer

When debugging through the "c:\\" is considered as a classpathEntry. In the 
ConfigurationLoader.collectEventualSourceDirectories() line 123 when the 
classpathEntry.getParentFile() is called i returns "null" and the same method 
is called recursively with the null value. Do you have any idea why it is 
happening?

- I Have non maven project (project Core for the business logic and separate 
gwt project for the UI, the gwt project has visibility/dependency on the Core) 
- Added all of the required libs
- in the root of the test classpath created META-INF/gwt-test-utils.properties

Its quite frustrating because I really like the gwt-test-utils framework just 
cant run it. Thank you very much for your reply!
