Not running class initializer for InetAddress causing ServerSocket failures
---------------------------------------------------------------------------
Key: RVM-700
URL:
http://jira.codehaus.org/browse/RVM-700 Project: RVM
Issue Type: Bug
Components: Runtime: Class Library: GNU Classpath
Affects Versions: 3.0.1
Reporter: Ian Rogers
Assignee: Ian Rogers
Fix For: 3.0.2
Suriya Subramanian noticed that ServerSockets had broken in recent RVM releases, this was due to a change in the primordials and not adding the corresponding execution of the class initializer. If we'd be running mauve or similar regressions this would have been picked up. Below is Suriya's original e-mail:
Hi all,
I have a simple program that demonstrates different behavior with different
versions of Jikes RVM. Jikes RVM 2.9.1 produces same output as Sun's JVM.
3.0.1 causes a SocketException when trying to create a new ServerSocket.
I am trying to run Jetty webserver (
http://www.mortbay.org/jetty/) and it
comes down crashing with a segmentation fault on 3.0.1. The program below
might explain why.
Does anyone an idea why this fails? Any solutions/workarounds? Would using
a different version of classpath help? I am working towards PLDI and I'd be
really grateful for a quick response.
$ cat Server.java
public class Server {
public static void main(String a[]) {
try {
new java.net.ServerSocket(8000);
System.err.println("No exception");
} catch (java.io.IOException ioe) {
System.err.println(ioe.toString());
}
}
}
$ java Server
No exception
$ ./jikesrvm-2.9.1/dist/prototype_ia32-linux/rvm Server
No exception
$ ./jikesrvm-3.0.1/dist/prototype_ia32-linux/rvm Server
java.net.SocketException: Unresolved address
Thanks,
Suriya
