The File class toURL() method does not escape "excluded" URL
characters when mapping a file path to a file: URL. For example, space
characters or '#' characters etc. should be escaped with a '%' followed by the
hexidecimal encoding of the character.

	See RFC 2396 section 2.4.3.

1. Make directory, which name containts "!" sign and go to it.
2. Create java file like:
import java.net.*;
import java.io.*;
public class q
{
    public q()
    {
        try {
            URL u = getClass().getResource("myresources");
            System.out.println("" + u);
            InputStream in = u.openStream();
            System.out.println("" + in);
            InputStreamReader inr = new InputStreamReader(in);
         } catch (Throwable t)
        {
            t.printStackTrace();
        }
    }
    
    public static void main(String args[])
    {
        q qq = new q();
    }
}

3. Create file named "myresources"
4. Place q.class and myresources to JAR file, by example "test.jar"
5. Run java -classpath test.jar q
6. Look at console:
jar:file:/M:/test/!/test.jar!/myresources
java.util.zip.ZipException: error in opening zip file

        at java.util.jar.JarFile.<init>(JarFile.java:71)
        at java.util.jar.JarFile.<init>(JarFile.java:58)
        at sun.net.www.protocol.jar.JarFileFactory.get(JarFileFactory.java:76)
        at sun.net.www.protocol.jar.JarURLConnection.connect

        at sun.net.www.protocol.jar.JarURLConnection.getInputStream

112)
        at java.net.URL.openStream(URL.java:818)
        at q.<init>(q.java:10)
        at q.main(q.java:21)

7. Place all files in, by example, "test" directory.
Run again. All is OK.

Problem occurs because "!" is Jar resource delimiter sign, and I think
that either "!" must not be resource delimiter sign, or
JarURLConnection::getResource() needed to be changed.
