Inheritance Depth Record

See How Deep is Your Hierarchy? for a tool on how to probe your jar files.

To win fame for discovering a deep open-source hierarchy, you have to reveal the project and the class that exceeds 9 levels. You may post anonymous submissions for the proprietary records. We will take your word for it.

• Open Source: Record held by Rob Mulcahey, Current Inc, Colorado Springs for discovering 12 levels of inheritance in Apache's Batik.
• Proprietary: Record held by Cameron Purdy, Tangosol, for a class hierarchy going down 12 levels in their Tangosol Development Environment. In their defence, it is a GUI class.
• Proprietary Anonymous: Record held by anonymous subscriber, for a class hierarchy going down 14 levels, also a GUI class.
