-------------------------------------

             Summary: StackOverflowError in DefaultDependencyNode.accept
                 Key: MRESOLVER-38
                 URL: https://issues.apache.org/jira/browse/MRESOLVER-38
             Project: Maven Resolver
          Issue Type: Bug
          Components: resolver
    Affects Versions: Maven Artifact Resolver 1.1.0
            Reporter: Andreas Sewe
         Attachments: maven-resolver-demos.patch

I noticed a {StackOverflowErrror}} when trying to build the classpath for {{org.webjars.npm:n3-charts:2.0.17}} using Maven Resolver 1.1.0.

I’ve managed to produce a minimal example based on the {{maven-resolver-demos}} from the {{master-with-demos}} branch. To reproduce, just apply the attached patch to the branch (tried this with commit [{{84a32a86}}|https://github.com/apache/maven-resolver/commit/84a32a866ff27d4df75124074fd925588f4a574d]) and run the {{GetDependencyTree}} example:

(Note: The patch changes the {{plexus-utils}} version as well, as I was getting a {{ClassNotFoundException}} for {{org.codehaus.plexus.util.xml.pull.EntityReplacementMap}} otherwise.)
