Please review the code change at http://cr.openjdk.java.net/~weijun/8130302/webrev.00/
I didn't abandon -providerClass and go all the way to -provideName because -providerClass has a sub-option -providerArg that can be used to further configure the provider. Also I think we still need to support legacy providers that are not defined in modules.
With this fix, -providerClass accepts both a provider name and a provider class name. Some doc change will be needed.
Thanks Max
