public static @interface Java4C.StringJc
The CharSequence reference should be used as a StringJc instance.
It is applicable if the CharSequence variable in Java is set only from a StringBuilder or a String,
it is without conversion. String and StringBuilder/StringBuffer implements the CharSequence interface.
If the CharSequence comes from any other instance, it can't be converted to a StringJc in C,
then this annotation should not be used.
