public static <T> T convert(String s,
                            Class<? extends T> clazz,
                            Object defaultValue)
```
    Converts a String to a given class if a TypeConverter is available for that class. Falls back to the provided default value if the conversion is unsuccessful. However, if the default value is also invalid, then null is returned (along with a nasty status log message).
    
    Parameters:
    
    s - the string to convert
    
    clazz - the class to try to convert the string to
    
    defaultValue - the fallback object to use if the conversion is unsuccessful
    
    Returns:
    
    the converted object which may be null if the string is invalid for the given type
    
    Throws:
    
    NullPointerException - if clazz is null
    
    IllegalArgumentException - if no TypeConverter exists for the given class
