>          Components: Core
>    Affects Versions: 2.0.0-beta-1

> I filed this as a bug though it is a clear usage error. But since this might happen more often I think it should be handled more gracefully and informatively:
> If a configuration is specified to extend itself like in here:
> {quote}
>  <configurations>
>                 <conf name="compile" visibility="public" extends="compile"/>
>                 <conf name="runtime"/>
>  </configurations>
> {quote}
> Ivy doesn't complain but fails with a StackOverflowError:
> {quote}
> --- Nested Exception ---
> java.lang.StackOverflowError
>         at java.util.HashMap.getEntry(HashMap.java:344)
>         at java.util.LinkedHashMap.get(LinkedHashMap.java:280)
>         at org.apache.ivy.core.module.descriptor.DefaultModuleDescriptor.getConfiguration(DefaultModuleDescriptor.java:368)
>         at org.apache.ivy.core.resolve.IvyNode.addRootModuleConfigurations(IvyNode.java:596)
>         at org.apache.ivy.core.resolve.IvyNode.addRootModuleConfigurations(IvyNode.java:599)
>         at org.apache.ivy.core.resolve.IvyNode.addRootModuleConfigurations(IvyNode.java:599)
>         at org.apache.ivy.core.resolve.IvyNode.addRootModuleConfigurations(IvyNode.java:599)
> {quote}
> This might as well be valid for arbitrary configuration inheritance cycles, but I didn't tested this.
