javap, method com.sun.tools.javap.Main.run returns 0 even in case of class not found error

Having the following java class:

import java.io.File;
import java.io.PrintWriter;
import java.io.StringWriter;
import com.sun.tools.javap.Main;

public class TestJavap {

    public static void main(String args[])
            throws Exception {
        String[] params = new String[]{"-v", "eeTestJavap.class"};
        StringWriter sw = null;
        int result = 0;
        try (PrintWriter pw = new PrintWriter(sw = new StringWriter())) {
            result = Main.run(params, pw);
        }
        System.out.println("result " + result);
        System.out.println(sw.toString());
    }

}

and compiling and executing it with the following commands:

javac -classpath /path/to/jdk1.8.0/lib/tools.jar:. TestJavap.java
java -classpath /path/to/jdk1.8.0/lib/tools.jar:. TestJavap

The output is:

result 0
Error: class not found: eeTestJavap.class

Not sure if this is the intended behavior but it could be expected that in the case of a class not found or similar errors, the method should return an exit code different from 0.
