--------------------------------
Assignee: Xavier Hanin
> StackOverflowError when configuration extends itself
> ----------------------------------------------------
>
> Key: IVY-696
> URL: https://issues.apache.org/jira/browse/IVY-696
> Project: Ivy
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0.0-beta-1
> Reporter: Johannes Rudolph
> Assignee: Xavier Hanin
> Priority: Minor
> Fix For: 2.0
>
>
> 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.
