OCPJP Study Guide: Chapter 5 - Possible errata on Question #5

[John Schubert]

Suppose that we have the following property files and code. Which bundles are used on lines 8 and 9 respectively?

Dolphins.properties
name=The Dolphin
age=0

Dolphins_en.properties
name=Dolly
age=4

Dolphins_fr.properties
name=Dolly

//
//
//
//
Locale fr = new Locale("fr");
Locale.setDefault(new Locale("en", "US"));
ResourceBundle b = ResourceBundle.getBundle("Dolphins", fr);
b.getString("name");
b.getString("age");

...

The correct answer according to page 558 is:
D. Dolphins_fr.properties and Dolphins.properties

It should have been:
D. Dolphins_fr.properties and Dolphins_en.properties

Line 9 should find a match in the English resource file for "age" as it is the default locale (BTW en-US happens to be the default locale on my computer even though I'm in Europe, even without setting it explicitly).
This goes in accordance with table 5.7 in p.264: first we look for the requested locale, as it is not defined there we go to the default locale, and then we would hit the default file but in this case it doesn't need to.

Am I missing something here?

John,
It's right in the book. Really; give it a shot. The rules you quoted are for finding a resource bundle. Once Java finds one, it can only use the hierarchy. In other words, once it finds the French one, it is too late to switch to the default locale.

Table 5.7 is only used for finding the initial bundle. Once a bundle is found, table 5.8 comes into play. Which is what this question is testing you on.
