             Summary: Path.traverse() exception if Win10 junction points to non-existing directory
                 Key: GROOVY-10523
                 URL: https://issues.apache.org/jira/browse/GROOVY-10523
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 4.0.1, 3.0.11
         Environment: Windows 10
            Reporter: Dan DeRobertis


Summary: Win 10 {{Documents }}directory contains a junction {{My Music}} that points to a non-existent directory {{{}C:\Users\dan\Music{}}}.

Observation: _traverse()_ succeeds when using {{{}File{}}}, fails when using {{{}Path{}}}. Issue exists in Groovy 3 + JDK11 and Groovy 4 + JDK17.

// Path traverse throws
//   FileNotFoundException: C:\Users\dan\Documents\My Music
// note: "My Music" is a reparse point (junction) pointing to non-existing directory "Music"
