Hmm.  When I execute the tests specifying the target directory, I only 
get results only for tests under that directory (in this case, those 13 
tests under test/java/util/Locale).  I haven't used the open source 
version of 'jtreg' yet, so there could be some differences.

I usually run 'gnumake' under jdk/make/java/java to build Locale.java, 
which finishes pretty quickly.

Unlike the classes in java.lang, such as Character which is built quite 
early in the build process and affects other areas, Locale is pretty 
much safe for just building itself.  Not 100% sure, though.

BTW, the 'From' field of this list always is 
'locale-enhancement-dev at openjdk.java.net'.  This can be set to the 
poster's address by disabling the 'anonymous_list' general option.

HTH,
