Geek Records for Java

This page lists obscure records that should probably never have happened.

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 a whopping 53 levels. They know that this is ridiculous and far away from good design. It was implemented by a Java developer with limited Java experience. But the code is still in production and works from a business point of view.

Package Depth Record
