GwtRuntimePluginLoader (UberFire Backend Server 1.0.0.Beta6 API)

java.lang.Object
- org.uberfire.backend.server.plugin.GwtRuntimePluginLoader

```
@Dependent
public class GwtRuntimePluginLoader
extends Object
```
Processes and activates deployed plugin jars. The corresponding .js files are registered with the PluginRegistry and are added to the host page's <head> element by Errai, so that all plugin scripts execute before the web application's main script runs. This is required to ensure plugins and their managed beans are discoverable by Errai's bean manager when the main application bootstraps.
