The automated tests for Media frequently call new Media() with no URL, which sends a null to the "create" action. In the past, this got turned into the string "null" in Java, which was handled as a file named "null" that didn't exist, and nothing crashed.
DataResource is fine with the files not existing, but it's not fine with "null" as a filename since it neither has a URL scheme nor is it an absolute path. Is there a reason why new Media() should work rather than throwing IllegalArgumentExceptions for trying to read files with relative paths? Should I detect and gracefully handle null being given as the media URL in Javascript? In Java? Should I instead change the mobile-spec tests to use "file:///dummy" or similar? Braden
