The older versions remain for historical reasons only. The SecurityPriceService-2014-11-12 variant does require additional configuration since it relies on a DOM level 3 implementation which isn't unlocked by default from Wildfly 8. The SecurityPriceService-2014-12-17 variant uses an outdated testcase with an ISIN that doesn't exist any longer. The latest SecurityPriceService-2017-01-03 variant has been adapted to the current WildFly 10.
