Description:
    Constructor of java.util.jar.JarOutputStream(OutputStream,Manifest) throws ZipException when JarOutputStream is passed as argument. In other words, wrapping JarOutputStream twice throws ZipException. Please execute the code below to reproduce:

<code>
import java.io.*;
import java.util.jar.*;

public class JarOutputStreamTest {
    public static void main(String...args) throws IOException {
          JarOutputStream jos = new JarOutputStream(new FileOutputStream("new.jar"));
          JarOutputStream jos2 = new JarOutputStream(jos,new Manifest());

    }
}

</code>
