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
Priority: Minor
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}

This might as well be valid for arbitrary configuration inheritance cycles, but
I didn't tested this.
