Hi [~cziegeler]! :)

If I am not wrong, Java7 and Java6 JXM APIs are exactly the same, so I configured the main printer to fallback to the {{Jdk16ThreadDumper}}, in case the JVM version is _1.7_, see the {{CompositeThreadDumper}} class in the patch.

Apologize for not having had a look at Java8 APIs, this is something I can provide a new patch to fill that lack.

>          Components: Web Console
>    Affects Versions: webconsole-3.1.8

> 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.
