We have a NullPointerException during integration testing. When getting the default thumbnail for document, an exception was thrown.

I believe this is caused by the side effect of method FileUtils#getResourceFileFromContext(String), because the resource returned by class loader is nullable. This is not considered by method getFilePathFromUrl(URL).
org.nuxeo.common.utils.FileUtils.java
/**
* Retrieves the total path of a resource from the Thread Context.
*
* @param resource the resource name to be retrieved.
* @return the decoded path.
*/
public static String getResourcePathFromContext(String resource) {
URL url = Thread.currentThread().getContextClassLoader().getResource(resource);
return getFilePathFromUrl(url);
}
