Description

Part of the Confluence application start-up failure described in HARMONY-5424.

Confluence uses Avalaon, and as part of the start-up sequence is scanning the JAR file. Harmony ZIP code fails on this jar for some reason.

Here's a simple reproducer (point to the confluence install dir as appropriate):

import java.io.IOException;
import java.util.Enumeration;
import java.util.jar.JarEntry;
import java.util.jar.JarFile;

public class JarFileTest {

public static void main(String[] args) throws IOException {

JarFile jar = new JarFile(
"/confluence-2.7.1-std/confluence/WEB-INF/lib/avalon-framework-4.2.0.jar");

Enumeration<JarEntry> entries = jar.entries();
while (entries.hasMoreElements())

{ JarEntry entry = entries.nextElement(); System.out.println(entry); }

jar.close();
}
}

On RI the above program prints out ..
