Using deprecated '-debug' fallback for parameter name resolution. Compile the affected code with '-parameters' instead or avoid its introspection

I am using Spring Boot 3.0.0, Eclipse IDE 2022-12, Java language level/JDK 19.

How to avoid/resolve this warning?
P/S: Comment about not dupplicated question. In this question and solution https://stackoverflow.com/a/74601911/3728901 , use maven-compiler-plugin , not spring-boot-maven-plugin .

This is a known bug and there is a Spring Issue for it. But it is not harmful and you do not need to take any action unless you just don't want warnings in your logs.
From the issue:
"It looks like the core bean factory is unnecessarily retrieving constructor parameter names during the constructor autowiring algorithm, despite no constructor argument names having been specified. That's a bug we're going to fix in [Spring Framework] 6.0.3."
and
"For the time being, you may simply disable the warn log category for org.springframework.core.LocalVariableTableParameterNameDiscoverer. There is unnecessary reading of class files in the meantime but otherwise no harm for your application."

java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: News is not mapped [from News where status =: active]

I connected Spring 5.0.19.RELEASE and Hibernate 5.2.10.Final.
I'm getting an error: java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: News is not mapped [from News where status =: active].
The same error is also obtained with other requests (for example "from News").
The work of the application reaches the DAO layer and executes a query from the database.
When I trying to get information from BD and display this list in the web app.
I'm a newbie in Java.
I tried the options below:
why-org-hibernate-hql-internal-ast-querysyntaxexception-customer-is-not-mapped
Hibernate error - QuerySyntaxException: users is not mapped [from
users]
but it doesn't work.
I hope to get help in my confused situation.

There are lot of posts on stackoverflow in which addressing the same issue. But I was unable to find a definite solution for this.
Please help

You could try this:
Query<News> theQuery = currentSession.createQuery("select news from News news where news.status = :active", News.class);
theQuery.setParameter("status", active);
return theQuery.getResultList();

Hibernate Session null-pointer exception

I have been stuck with this issue for days cannot figure it out, I mean I know the sessionFactory must be null as the stacktrace indicates but I cannot understand why? The exception always comes back to the line:
Session session = hibernateUtil.getSessionFactory().getCurrentSession();
Here is a trimmed version of the stacktrace:

Your hibernateUtil field is null. In fact, why did you introduce an instance field for that? Nothing is injected into it and you call a instance method on this null field. Make the method static as:
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
and then :
Session session = HibernateUtil.getSessionFactory().getCurrentSession();

Try This :-
Replace your HibernateUtil class with this one:-
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.SessionFactory;
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
try {
sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
} catch (Throwable ex) {
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
and you should also try
SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
Session session = sessionfactory.openSession();
instead of
Session session = hibernateUtil.getSessionFactory().getCurrentSession();
I hope it will work,.
Updated
#Autowired
private HibernateUtil hibernateUtil;

The null-pointer exception was eradicated when I changed the line:
Session session = hibernateUtil.getSessionFactory().getCurrentSession();
to:
session = HibernateUtil.createSessionFactory().openSession();
I thought the problem was that I was originally attempting to get a session that was currently closed but I'd have expected to receive the 'session is closed!' message that I've seen previously? Anyway the null-pointer exception has been resolved.
(the code within the createSessionFactory() method in HibernateUtil was not changed)

Originally this issue occurs when the request sends an accept header that differs from the response's content-type. I don't know if this is the case, there's not enough source provided.
However, another a bit more trickier situation when the same error occurs is when the framework is not able to convert the response to an appropriate representation, e.g. on account of bad getters/setters or missing dependencies.
In the code you posted I see an issue with your dependencies. Spring 4.1 needs minimum Jackson 2.1, and in the version Jackson 2 and above a package change occurred from codehaus to fasterxml. Replace the two of your Jackson dependencies with the following one
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.1.2</version>
</dependency>
or better yet go for a newer version. Single dependency is enough it will transitively pull com.fasterxml.jackson.core:jackson-annotations:jar and com.fasterxml.jackson.core:jackson-core:jar

I think you might have to ensure that your Request is having the following in your header:
GET
Accept: application/json

Please help me in fixing this error.....
Thanks in advance.....

I tested same example in my local machine with the following dependencies.
file paths are not correct if you are running it in windows.
check the code below.

It worked for me.

Did you include the dependency for Xstream in your maven file? If you are using maven please add the following to your project file:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-xstream</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>
The error clearly states you are missing a component
