False positive S4248 with Lombok @UtilityClass

Rules and Languages Report False-positive / False-negative...

On SonarCloud, SonarJava raises false positives for regex Patterns when using Lombok @UtilityClass.
S4248 requires compiled patterns to be assigned to constants, but does not recognize the static keyword generated by @UtilityClass.

Example:

import java.util.regex.Pattern;

import lombok.experimental.UtilityClass;

@UtilityClass
public class Foo
{
    // S4248: Refactor this code to use a "static final" Pattern.
    private final Pattern PATTERN = Pattern.compile(".*");
}

Hello, welcome to the community!

Thanks for the feedback, indeed, this is a wrong behavior of the rule in the presence of Lombok.

I created a ticket (SONARJAVA-3379) to keep track of this issue.

Best,
Quentin
