That's weird, because looking at this http://download.java.net/java/jdk9/docs/api/java/net/URLClassLoader.html#getURLs-- (http://preview.tinyurl.com/yat6a6oq), it looks like that method is still supplied in Java 9.

But I'm not a Java person at all, so I could easily be wrong about this.

It compiled successfully under JDK_1_8_0_144.  Has anyone else seen this?
