java.util.spi.LocaleServiceProvider prevents threetenbp to be used on Google App Engine

[clementdenis]

org.threeten.bp.format.DateTimeTextProvider and org.threeten.bp.format.DateTimeFormatStyleProvider both implement java.util.spi.LocaleServiceProvider, which is not in the Google App Engine JRE whitelist: https://cloud.google.com/appengine/docs/java/jrewhitelist

I'm not sure why this was implemented this way, but the corresponding class in java.time don't implement this interface.

Could the interface be removed and the method "public Locale[] getAvailableLocales()" added to each class to ensure backward compat and allow thretenbp to run on GAE?

I am happy to see pull requests to enhance use on Android. I don't have an Android dev environment nor much spare time, so that it the only realistic way to achieve a change ;-)

Thanks for your very fast answer, but I'm talking about Google App Engine here (the Google's PAAS).

I checked the DateTimeTextProvider in JDK8, the LocaleServiceProvider interface never made it when the code was imported into the JDK.

As threetenbp is a backport, why not remove this interface to make it more like JSR310?
