使用 WildFly 18.0.1 创建多个 @Dependent 实例来测试内存泄漏

@Dependent
public class Book {
    @Inject
    protected GlobalService globalService;

    protected byte[] data;
    protected String id;

    public Book() {
    }

    public Book(GlobalService globalService) {
        this.globalService = globalService;
        init();
    }

    @PostConstruct
    public void init() {
        this.data = new byte[1024];
        Arrays.fill(data, (byte) 7);
        this.id = globalService.getId();
    }
}


@ApplicationScoped
public class GlobalFactory {
    @Inject
    protected GlobalService globalService;
    @Inject
    private Instance<Book> bookInstance;

    public Book createBook() {
        return bookInstance.get();
    }

    public Book createBook2() {
        Book b = bookInstance.get()
        bookInstance.destroy(b); …
