Locale related utility classes are maintained by the i18n group - right?

Hi there,
in java.util.Currency, the currency.data is loaded from $JRE_DIR/lib.
I'm having a problem with this in the JamaicaVM, when an application is
built into a single bundle for use on an embedded machine. There is no
JRE installed on that machine, and this file can't be loaded. I suggest
to fall back to loading this file via the ClassLoader. See attached
patch. This should affect normal behaviour, and only adds the option to
put this file in the (boot) classpath instead. What do you think?
