SonarQube静态方法中的假阳性“应删除未使用的私有方法”

Question

Example code:

public static String foo(){
 return bar();
}

private static String bar(){
 return "";
}

SonarQube marks bar() function as unused, but SonarLint (IntelliJ, version 2.7.1.1640) works fine. I have installed latest version of SonarQube (6.2) and latest version of Java plugin (4.5.0.8398), but still have this issue - i thought this issue was fixed? Is this some kind of regression bug? Thanks for your help.

UPDATE:

Above example was too trivial, i manage to specify problem: it looks like a problem with primitive arguments passed to function, for example this is marked as unused:

public static String foo( SomeClass a ) {
    return bar( a.getChar() );
  }

  private static String bar( char a ) {
    return String.valueOf( a );
  }

if i pass hardcoded value to bar (like bar('a') ) everything works fine (or even when i pass something like bar("string".charAt(0) ) ). SomeClass.getChar() return 'char' so it is not a problem with boxing primitives.

SOLUTION: as @Michael - SonarSource Team suggested, there was a problem with dependencies bytecodes. I disabled teamcity Sonar runner plugin and now run sonarqube via Gradle plugin.
