> Key: HARMONY-1585
> URL: http://issues.apache.org/jira/browse/HARMONY-1585
> Project: Harmony
> Issue Type: Bug
> Components: Classlib
> Reporter: Denis Kishenko
> Assigned To: Mark Hindess
> Attachments: 1585-Empty PathIterator.patch
>
>
> Harmony implementation of Arc2D, Ellipse2D and RoundRectangle2D behavior differs from RI if shapes are empty. Harmony returns absolutely empty PathIterator while RI returns non empty PathIterator with zero points.
