Consider the following snippet:

package a;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;

public class MultiCatch {
	public static void main(String[] args) {
		File file = new File("");
		try (BufferedReader reader = new BufferedReader(new FileReader(file))) {
			System.err.println("reading...");
		}
		catch(NullPointerException | IllegalArgumentException ex){}
	}
}

Steps:

1. once pasted there should be 2 errors about un-caught exceptions
2. quick fix the FileNotFoundException to add the exceptions to the existing list of exceptions
3. save

Notice at this point your code has an error about FileNotFoundException being covered by IOException. Perhaps the quick-fix could be enhanced to detect this scenario (redundant exceptions) and avoid the 'already caught error'?
