============================================================================
Gregory's mods to the test cause the exact same repeated exception on drlvm and RI. On both jit and interpreter. So there is some classlib compatibility crud here I don't understand. But the symptoms are just the same.
We can't do more, we should close the bug.

[jira] Commented: (HARMONY-1109) [drlvm] debug build crashed on the
URL.openStream() method
Posted by "Gregory Shimansky (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/HARMONY-1109?page=comments#action_12427042 ]
Gregory Shimansky commented on HARMONY-1109:
--------------------------------------------
The test seems to be invalid. It actually causes SOE, not NPE but other VMs treat it as an NPE because they use hardware exceptions. It looks like SOE engine in drlvm just isn't mature enough to handle this situation, I am not yet sure why.
I've created a test modification which shows how it really works:
import java.net.*;
import java.io.*;
public class test1109 {
public static void main (String[] args) {
try {
new URL("","nns9", 6, ":80", new TestURLStreamHandler()).openStream();
} catch (Exception e) {
e.printStackTrace();
}
}
}
class TestURLStreamHandler extends URLStreamHandler {
protected URLConnection openConnection(URL arg) throws IOException {
try {
System.out.println("arg = " + arg);
(new Throwable()).printStackTrace();
return arg.openConnection();
} catch (Throwable e) {
return null;
}
}
}
The exception stack trace is growing and growing. But I didn't understand why it happens. I looked at classlib code and didn't find out how it can cause infinite recursion. The good thing is that RI does this as well so maybe classlib just has a "compatibility bug" :)
DRLVM in default mode handling of SOE doesn't handle this test correctly. On the other hand drlvm with -Xint option throws the correct SOE exception while even RI running on interpreter (-Xint) throws NPE for some reason :)
