"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:

public final class Test {

	private final List<String> 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:

public final class Test {

	private final List<String> collection;

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

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

}

Did this work correctly in an earlier version?

No
