[jira] Created: (IVY-397) NullPointerException when resolving

NullPointerException when resolving
-----------------------------------

                 Key: IVY-397
                 URL: https://issues.apache.org/jira/browse/IVY-397
             Project: Ivy
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.4.1
         Environment: JDK 1.6 on Win/XP
            Reporter: Luca Buraggi


I know it is very difficult to reproduce ...
The bug disappear if I modify the ivy.xml of my project, commenting out some depency elements. I suspect some evil circular dependency but I didn't yet find it. I include the stack trace and the <dependencies> element of my ivy.xml

[jira] Updated: (IVY-397) NullPointerException when resolving

Posted by "Luca Buraggi (JIRA)" <ji...@apache.org>.
     [ https://issues.apache.org/jira/browse/IVY-397?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Luca Buraggi updated IVY-397:
-----------------------------

    Description: 
I know it is very difficult to reproduce ...
The bug disappear if I modify the ivy.xml of my project, commenting out some depency elements. I suspect some evil circular dependency but I didn't yet find it. I include the stack trace and the <dependencies> element of my ivy.xml

Seems the same bug of issue IVY-379

>             Project: Ivy
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 1.4.1

>            Reporter: Luca Buraggi

> I know it is very difficult to reproduce ...
> The bug disappear if I modify the ivy.xml of my project, commenting out some depency elements. I suspect some evil circular dependency but I didn't yet find it. I include the stack trace and the <dependencies> element of my ivy.xml

> The bug disappear if I modify the ivy.xml of my project, commenting out some depency elements. I suspect some evil circular dependency but I didn't yet find it. I include the stack trace and the <dependencies> element of my ivy.xml
