DateTokenConverter class has a problem

[TasMot]

This method:

`
public String convert(Object o) {
if (o == null) {
throw new IllegalArgumentException("Null argument forbidden");
} else if (o instanceof Date) {
return this.convert((Date)o);
} else if (o instanceof Instant) {
return this.convert((Instant)o);
} else {
String var10002 = String.valueOf(o);
throw new IllegalArgumentException("Cannot convert " + var10002 + " of type" + o.getClass().getName());
}
}

`
It generates the proper "String.valueOf(o)" and then it throws an exception. So, the proper string value of the object is never returnd.
