Add support for the locale gl_ES in the jre for date, currency and date format. This locale identifies the galician language.

The EU is acception the galician but it is not promoted as a official EU language. In the spain it has status of official language.
See: http://en.wikipedia.org/wiki/Galician_language
The request is for gl_ES so it sound reasonable to have it implemented.

I cannot tell about Galician as European official language but I can secure that Galician is a Spanish official language.

(Constitución del Reino de España, 1978)

As is in ISO 639 standart: ISO Galician  gl  LANG_GALICIAN.

Galician is considered as an official language by Spanish kingdom and international comunity.

All Corporations and companies of reputation over the world like ISO, Microsoft (Windows XP and Office are translated to Galician), Google,  etc. Cosider galician as an official language.

European union currently has 11 official languajes + nine  new official languages.  Just  the main language of a country is recognized as official language.

There are nearly 3 million people in Galicia and a few people in Asturias (another area in Spain) that use Galician too. It

There are nearly 3 million people in Galicia and a few people in Asturias (another area in Spain) that use Galician too. It's an official Spanish language recognized by the Constitution and the law. It is as important here as Spanish and it's very used in bureaucracy.

Including it cant be bad

Here you have a link to the Spanish Government proposal to EU about the co-officiality of Catalonian, Basque, Galician and Valencian:
http://www.es-ue.org/Default.asp?lg=1&section=4
There

Galician is a official language in Spain, there is support for other languages in the same situation (not necessary official languages at the European Union) .

I support this RFE, as I support solving bug (not RFE as Sun say) for Serbia and Montenegro locals.

First part of Locale is country, second - language.
Why not es_GL?

RTFM
public Locale(java.lang.String language, java.lang.String country, java.lang.String variant)
