/**
 * A handler for @Dependent scoped beans used by sisu-guice.
 * <p/>
 * The DefaultPlexusContainer created by MavenEmbedderUtils for KIE's programmatic use of maven-core
 * and Aether tries to wire-up all beans on the classpath. The KIE Workbenches contain @Dependent classes
 * defining client-side Uberfire Perspective definitions. These are filtered from the webapp WARs as they are
 * client-side only and handled by Errai's CDI implementation; however when ran from within an IDE
 * the classes exist on the classpath and sisu-guice fails to bind @Dependent scope.
 * <p/>
 * This class is a work-around for running the KIE Workbenches in GWT Hosted Mode.
 * <p/>
 * See https://github.com/sonatype/sisu-guice/issues/10
