Hi Martin
Thank you for your answer.
1) I don't inject Test class anywhere.
2) I modified init and destroy methods:
public void init(@Observes @Initialized(ApplicationScoped.class) Object init) {
System.out.println(init);
System.out.println("Test was initialized");
}
public void destroy(@Observes @Destroyed(ApplicationScoped.class) Object init) {
System.out.println(init);
System.out.println("Test was destroyed.");
}
Now on bundle start:
Test was created.
Application context initialized.
Test was initialized
java.lang.Object at 48813e62
Test was initialized
Now on bundle stop:
java.lang.Object at 48813e62
Test was destroyed.
Test was created.
Application context destroyed.
Test was destroyed.
