The following program shows two nearly identical error
messages, but see that the source range highlighted is
inconsistent.
// --------------- 8<----------------------
import java.io.*;
public class X {
	public static void main(String[] args) {
		try {
			System.out.println();
			Reader r = new FileReader(args[0]);
			r.read();
		} catch(RuntimeException | Exception e) {
			e.printStackTrace();
		} catch(FileNotFoundException | IOException e) {
			e.printStackTrace();
		}
	}
}

class Y {
	public static void main(String[] args) {
		try {
			throw new DaughterOfFoo();
		} catch(SonOfFoo | DaughterOfFoo e) {
			e.printStackTrace();
		}
	} 
}

class Foo extends Exception {}

Junits already exist :)
org.eclipse.jdt.core.tests.compiler.regression.TryStatement17Test.test010()
shows the preferred behavior while 
org.eclipse.jdt.core.tests.compiler.regression.TryStatement17Test.test003()
shows the less desirable behavior.
