[jira] Created: (HARMONY-2871) [classlib][luni] URLClassLoader
invalidates it's state if there is invalid URLs in its urls list
[classlib][luni] URLClassLoader invalidates it's state if there is invalid URLs in its urls list
------------------------------------------------------------------------------------------------
Key: HARMONY-2871
URL: http://issues.apache.org/jira/browse/HARMONY-2871
Project: Harmony
Issue Type: Bug
Components: Classlib
Environment: WinXP
Reporter: Mikhail Markov
Priority: Critical
The test below passed on RI, but fails on Harmony.
Output on Harmony:
FAILED: java.lang.NullPointerException
Output on RI:
PASSED.
The cause is that URLClassLoader sets URL's in it's internal list which it could not open to null and throws NPE during the next attempt to load the class.
-------------------- Test.java ------------------------
import java.net.URL;
import java.net.URLClassLoader;
public class Test {
public static void main(String [] args) throws Exception {
URLClassLoader cl = new URLClassLoader(new URL[] { new URL("file:/c:/foo.jar") });
try {
Class.forName("foo.Foo", false, cl);
} catch (Exception ex) {
// Don't care
}
try {
Class.forName("foo.Foo", false, cl);
System.out.println("FAILED: no exceptions");
} catch (ClassNotFoundException cnfe) {
System.out.println("PASSED.");
} catch (Exception ex) {
System.out.println("FAILED: " + ex);
}
}
}

Mikhail Markov updated HARMONY-2871:
------------------------------------
Attachment: URLClassLoader.patch
Here is the patch for the class loader - it modifies the way URLClassLoader deals with invalid urls: it does not set the invalid urls to null in the internal list but put them into internal "excluded" list instead.
