   java runtime also supports global state (using static keyword) per container.
   
   _If an error occurs in the action code, global variables are not stored._
   
   ## Sample code
   
   ```java
   
   class Global {}
   
   public class Application {
       private static Global global;
       public static JsonObject main(JsonObject args) {
           if (global == null) {
               System.out.println("global is null");
               global = new Global();
           } else {
               System.out.println("global is not null");
           }
           return new JsonObject();
       }
   }
   ```
