java.lang.ClassLoader.getResourceAsStream() method returns null value if:

1) resource is *existing empty* file and
2) classLoader is *sun.applet.AppletClassLoader* and
3) path in codebase is undicated via http schema


Example:
----------------------------------------------------------------
<applet
    code="TestApplet"
    codebase="http://jcklab8.russia.sun.com/set/java/jck/tmp/Yulia"
    width=600 height=400
    >
</applet>

****
import java.applet.*;
import java.io.InputStream;

public class TestApplet extends Applet {
    public void init() {
        ClassLoader cl = this.getClass().getClassLoader();
        if (cl != null) {
            try {
                String serName="tmp.ser";
                InputStream ins=cl.getResourceAsStream(serName);
                System.out.println("ins = "+ ins);
            } catch (Exception ex) {
                System.out.println(ex);
            }
        } else {
            System.out.println("ClassLoader == null");
        }
    }
}
******
Test output:
1) [ if tmp.ser == *empty* file]
ins = null

2) [ if tmp.ser == *NOT empty* file]
ins = sun.net.www.protocol.http.HttpURLConnection$HttpInputStream@1e6e305

*************

In case if codebase is indicated via file scheme, everything is ok:

--------------------------------------------------
<applet
    code="TestApplet"
    codebase="../IdeaProjects//Beans_bags//classes"
    width=600 height=400
    >
</applet>
*****
Test output:
1) [tmp.ser == *empty* file]
ins = www.MeteredStream@b23d12'>sun.net.www.MeteredStream@b23d12

2) [tmp.ser == *NOT empty* file]
ins = www.MeteredStream@9fa8f'>sun.net.www.MeteredStream@9fa8f
