h4. Generation of plugin metadata and packaging

To create the packaging for a plugin a special Maven packaging would be created with an accompanying life-cycle in order to create the plugin metadata required and create an archive of the plugin that can be consumed at runtime.

   * ThreadLocal is usually implemented with a WeakReference, which can have negative performance
   * properties; for example, calling WeakReference.get() on Android will block during an
   * otherwise-concurrent GC cycle.
