Re: [J2] Cornerstone stack overflow

[Barnhill William]

ok, based on some behavior I was seeing in the debugger I think I've 
tracked down the real culprit : PersistenceException.

I can reproduce the bug every time if I reduce the demoPersistence 
program down to just the following:

package org.apache.cornerstone.framework.demo.main;

import java.util.List;

import org.apache.cornerstone.framework.api.factory.CreationException;
import org.apache.cornerstone.framework.api.factory.IFactory;
import 
org.apache.cornerstone.framework.api.implementation.ImplementationException;
import org.apache.cornerstone.framework.bean.visitor.BeanPrinter;
import org.apache.cornerstone.framework.demo.bo.api.IGroup;
import org.apache.cornerstone.framework.demo.bo.api.IUser;
import org.apache.cornerstone.framework.init.Cornerstone;
import org.apache.cornerstone.framework.init.InitException;
import org.apache.log4j.PropertyConfigurator;
import org.apache.log4j.Logger;
import 
org.apache.cornerstone.framework.api.persistence.factory.PersistenceException;

public class DemoPersistence {
   public static final String REVISION = "$Revision: 1.6 $";
  
   public static void main(String[] args) throws InitException, 
ImplementationException, CreationException {
       // init log4j
       String log4jConfigFilePath = 
System.getProperty("log4j.configuration", "log4j.properties");
       PropertyConfigurator.configure(log4jConfigFilePath);
       Logger log = Logger.getLogger(DemoPersistence.class);
      
       //try {
          
           Cornerstone.init("../../runtime");
       try {
           try {
               throw new PersistenceException("dummy");
           }
           catch (PersistenceException ex) {
              log.error(ex);
              ex.printStackTrace();
           }           
       }
       catch (Throwable th) {
           java.io.StringWriter sw = new java.io.StringWriter();
           java.io.PrintWriter pw = new java.io.PrintWriter(sw);
           if (th.getCause()  == null) {
               pw.println("Cause is null");
           }
           else {
               th.getCause().printStackTrace(pw);
           }
           th.printStackTrace(pw);
           log.error("Error message is "+th.getMessage());
           log.error("Stack trace from previous error was: 
\n"+sw.getBuffer().toString());           
       }
  }
}

The output I get is :
org.apache.cornerstone.framework.api.persistence.factory.PersistenceException: 
dummy
   at 
org.apache.cornerstone.framework.demo.main.DemoPersistence.main(DemoPersistence.java:31)
Caused by: 
org.apache.cornerstone.framework.api.persistence.factory.PersistenceException: 
dummy
   ... 1 more

with
Caused by: 
org.apache.cornerstone.framework.api.persistence.factory.PersistenceException: 
dummy
   ... 1 more
repeated MANY more times.

The readme file in the cornerstone sample zip says that the 
StackOverflowError happens sometimes. For me it's happening everytime.

After doing some hunting and fiddling with logging I think I've 
tracked it down to the following msg/location:

2003-12-02 12:01:25,702 671  
[main@(org.apache.cornerstone.framework.persistence.factory.BasePersistentObjectCollectionFactory.createCollection(BasePersistentObjectCollectionFactory.java:325))] 

ERROR 
org.apache.cornerstone.framework.persistence.factory.BasePersistentObjectCollectionFactory  
- collection type definition missing; use 
'collection.instance.className' or 'collection.factory.className' or 
'collection.parent.name'

Has anyone fixed this already?

Does anyone have an idea how to fix this?

Also, will it make a difference right now if I use the version in CVS, 
or the one in the zip archive?
