 1. First, create an Annotation with annotated with @javax.inject.Scope; Example:
 
-    :::java
-    @Scope
-    @Retention(RetentionPolicy.RUNTIME)
-    @Target({ElementType.TYPE,ElementType.METHOD,ElementType.FIELD})
-    public @interface ACustomScope {}
+      :::java
+      @Scope
+      @Retention(RetentionPolicy.RUNTIME)
+      @Target({ElementType.TYPE,ElementType.METHOD,ElementType.FIELD})
+      public @interface ACustomScope {}
     
 2. Second, create an Extension to add the scope and a context for it. Example:
 
-    :::java    
-    public class ACustomScopeExtension implements Extension, Serializable {
+      :::java    
+      public class ACustomScopeExtension implements Extension, Serializable {
 	
-    	public void addACustomScope(@Observes final BeforeBeanDiscovery event) {
-    		event.addScope(ACustomScope.class, true, false);
-    	}
-
-    	public void registerACustomScopeContext(@Observes final AfterBeanDiscovery event) {
-    		event.addContext(new ACustomScopeContext());
-    	}
-    }
+      	public void addACustomScope(@Observes final BeforeBeanDiscovery event) {
+      		event.addScope(ACustomScope.class, true, false);
+      	}
+
+      	public void registerACustomScopeContext(@Observes final AfterBeanDiscovery event)
{
+      		event.addContext(new ACustomScopeContext());
+      	}
+      }
 
 3. Implement a javax.enterprise.context.spi.Context interface to hold the javax.enterprise.inject.spi.Bean
instances according to your needs
 
-    :::java
-    public class ACustomScopeContext implements Context, Serializable {
+      :::java

-      // Get the scope type of the context object.
-    	public Class<? extends Annotation> getScope() {
-    		return ACustomScope.class;
-    	}
-
-    	// Return an existing instance of certain contextual type or create a new instance by
calling
-    	// javax.enterprise.context.spi.Contextual.create(CreationalContext) and return the
new instance.
-    	public <T> T get(Contextual<T> contextual, CreationalContext<T> creationalContext)
{
-    		Bean bean = (Bean) contextual;
-    		// you can store the bean somewhere
-    		if (somewhere.containsKey(bean.getName())) {
-    			return (T) somewhere.get(bean.getName());
-    		} else {
-    			T t = (T) bean.create(creationalContext);
-    			somewhere.put(bean.getName(), t);
-    			return t;
-    		}
-    	}
-
-    	// Return an existing instance of a certain contextual type or a null value.
-    	public <T> T get(Contextual<T> contextual) {
-    		Bean bean = (Bean) contextual;

-    			return (T) somewhere.get(bean.getName());
-    		} else {
-    			return null;
-    		}
-    	}
+        // Get the scope type of the context object.
+      	public Class<? extends Annotation> getScope() {
+      		return ACustomScope.class;
+      	}
+
+      	// Return an existing instance of certain contextual type or create a new instance
by calling
+      	// javax.enterprise.context.spi.Contextual.create(CreationalContext) and return the
