SonarQube false positive squid:S1450 for @Getter (lombok) annotated fields

Question

I think I have found a false positive while using the @Getter annotation from Project Lombok .

In the following example class I got the warning "Private fields only used as local variables in methods should become local variables" ( squid:S1450 ).

public class Example {

    @Getter
    private String exampleField; // <-- squid:S1450

    public Example(final String value) {
        setExampleField(value);
    }

    private void setExampleField(final String exampleField) {
        this.exampleField = exampleField;
    }

}

Can someone confirm this? Is it a bug in the SonarQube rule or is there something wrong with my class or with my understanding of this rule or the @Getter annotation?

Just for the sake of completeness:

• Project lombok annotations or the generated methods are recognized correctly in other SonarQube rules. So I think my setup is fine.
• I have also tried to put the @Getter annotation on class level and I got the same warning.
• The warning is shown in SonarLint (in IntelliJ IDEA) and in the web interface of SonarQube. So I think it's not an error while executing the analyzer.
• I have bound the SonarLint pluign in IntelliJ IDEA to our SonarQube Server and this remote connection works.

I have tested with the following versions:

• SonarQube 6.0
• SonarQube Java Plugin 4.2
• SonarLint (for IntelliJ IDEA) 2.3.2
• IntelliJ IDEA 2016.2.5
• Java 8
