Bug - unused method parameter in lambda expression.

[kamilb...@gmail.com]

Hi, when a method parameter is used only as lambda parameter, then sonar implies that this parameter is unused.

Sonar version: Version 6.4 (build 25310)

private User deleteUserPrivileges(final User user, final Set<String> privilegesToDelete) {
  if (user == null) {
    return null;
  }
  user.getPrivileges()
    .stream()
    .removeIf(m -> privilegesToDelete.contains(m.getAsString()));
  return user;
}

I am getting the following sonar error:

Remove this unused method parameter "privilegesToDelete".

Hello,

Can you please specify which version of the SonarJava plugin is installed on your SQ instance?

I would also need a self-contained code snippet in order to reproducer the issue and start investigation. Your case seems close from the case depicted in SONARJAVA-2115, but I self-contained example would help me to tell more.

Cheers,

Michael
