Description

The Felix Web Console currently has an embedded plugin only using traditional Java API. Sling has a Web Console plugin leveraging the Java 5 JMX APIs.

These two should be consolidated and extended such that:

• Separate bundle (not embedded in the Web Console Bundle)
• one single plugin in Apache Felix
• Uses Java 6 JMX API if available
• Falls back to Java 5 JMX API if not Java 6
• Falls back to regular Java API as a last step
• Provide Gogo Shell Commands

The advantage of using Java 6 API is to be able to inject lock information in the thread dumps to be able to followup on deadlock and similar situations.
