negora opened a new issue, #4402:
URL: https://github.com/apache/netbeans/issues/4402
### Apache NetBeans version
Apache NetBeans 14
### What happened
Suppose that I've 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<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:
```java
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
### 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
