"Unbalanced read/write with collections" hint fails for fields initialized in constructor

### Apache NetBeans version

Apache NetBeans 14

### What happened

I've a Maven project of type *jar*. Suppose that I also have a class with a single field of type `List`. Then, I initialize that field in the declaration itself. If I never add any element to that collection, NetBeans properly warns me that *The collection is never added to*.

However, if I initialize the field in the constructor, NetBeans seems to be unable to detect that I still have not added any element to the collection.

### How to reproduce

In this piece of code, NetBeans correctly detects that no element has been added to the `collection` field:

```java
public final class Test {

private final List collection = new ArrayList<> ();
// ^^^ WARNING! The collection is never added to.

public Test () {
}

public boolean isEmpty () {
return collection.isEmpty ();
}

}
```

However, if I initialize the field in the constructor, the hint is never shown:

```java
public final class Test {

private final List collection;

public Test () {
collection = new ArrayList<> ();
}

public boolean isEmpty () {
return collection.isEmpty ();
}

}
```

### Did this work correctly in an earlier version?

No

### Operating System

Debian GNU/Linux 11.4 (Bullseye)

### JDK

OpenJDK Runtime Environment (build 17.0.3+7-Debian-1deb11u1)

### Apache NetBeans packaging

Apache NetBeans binary zip

### Anything else

_No response_

### Are you willing to submit a pull request?

No

### Code of Conduct

Yes

Reproduce the warning in a Java Maven jar project using the two Test examples, comparing field-declaration initialization with constructor initialization. Done means the “The collection is never added to” hint also appears when the List field is initialized in the constructor.
