Loading sequence of service provider is changed

Beginning from Java 8 b55, when there are mutiple provider-configuration files with same name, the sequence of loading the service provider is changed.

For exmaple,
pseudolocales1.jar and pseudolocales2.jar are all in the java extension directory.

pseudolocales1/META-INF/services/java.util.spi.CurrencyNameProvider points to CurrencyNameProviderImpl1
pseudolocales2/META-INF/services/java.util.spi.CurrencyNameProvider points to CurrencyNameProviderImpl2

Before 8 b55, for example, in 8 b54, JRE loads CurrencyNameProviderImpl1 first and then CurrencyNameProviderImpl2, but from 8 b55, CurrencyNameProviderImpl2 is loaded first.
