Subject [jira] Created: (HARMONY-1756) Dynamic class loading work incorrectly
Date Fri, 06 Oct 2006 13:54:21 GMT
Dynamic class loading work incorrectly
--------------------------------------

                 Key: HARMONY-1756
                 URL: http://issues.apache.org/jira/browse/HARMONY-1756
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Nikolay Chugunov


Dynamic class loading work incorrectly:
Code for reproduction:
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import junit.framework.TestCase;

public class Bug extends TestCase {
    private static String className = "EmptyClass";

    public void test() throws Exception {
        MyClassLoader classLoader = new MyClassLoader();
        System.out.println("Check point");
        classLoader.loadClass(className).newInstance();
        System.out.println("PASSED");
    }

    private class MyClassLoader extends ClassLoader {
        private MyClassLoader() throws IOException {
            InputStream in = new FileInputStream(
                "C:\\" + className + ".class");
            byte[] b = new byte[in.available()];
            in.read(b);
            in.close();
            defineClass(className, b, 0, b.length);
        }
    }
}
public class EmptyClass{
}

To reproduce compile classes and then move EmptyClass class to
C:\ directory which is not in class path and then run this test.

Output on RI 1.5:
Check point
PASSED

Output on Harmony r450941:
Check point
java.lang.ClassNotFoundException: Can not find class EmptyClass
	at java.lang.ClassLoader.findClass(Unknown Source)
	at java.lang.ClassLoader.loadClass(Unknown Source)
	at java.lang.ClassLoader.loadClass(Unknown Source)
	at Bug.test(Bug.java:15)
