[java:S2440] False positive: Classes with only "static" methods should not be instantiated

Clean Code Report False-positive / False-negative...

Hi all,

SonarCloud reports “Remove this instantiation of String” warning for the following pieces of Java code:

public static String getDChars( byte[] block, int pos, int length )
{
    return new String( block, pos - 1, length ).trim();
}

public static String getDChars( byte[] block, int pos, int length, String encoding )
{
    try {
        return new String( block, pos - 1, length, encoding ).trim();
    }
    catch ( UnsupportedEncodingException ex ) {
        throw new RuntimeException( ex );
    }
}

It’s obvious however that standard Java String class has non-static methods, so its instantiation is absolutely legitimate.
