[bv-dev] Making built-in constraints repeatable

Hi all, One of the things making life easier in Java 8 is repeatable annotations [1], for instance allowing to specify several @Pattern constraints, without the explicit usage of @Pattern.List. The transition is very smooth for BV built-in constraints, essentially we just need to mark them with @Repeatable, using the existing inner @List annotations as containers. Hence I didn't bother to create a separate proposal document but instead Guillaume and me have prepared changes for the API and the spec already. You can find the GitHub pull requests at [2] and [3], respectively. Speaking of changes to the API sources, we also increased the Java version to 8, bumped the project version to 2.0.0-SNAPSHOT and we've prepared a change for BVAL-486 [4] which is about not going through the provider resolver if a specific provider type is passed into bootstrapping via Validation#byProvider(). This was a tad inconvenient when e.g. explicitly bootstrapping the RI under OSGi, where you still had to provide a specific provider resolver. Please let me know if you have any concerns or other remarks on any of these by the end of the week. Silence will be taken as expression of agreement :) Cheers, --Gunnar [1] https://docs.oracle.com/javase/tutorial/java/annotations/repeating.html [2] https://github.com/beanvalidation/beanvalidation-api/pull/65 [3] https://github.com/beanvalidation/beanvalidation-spec/pull/111 [4] https://github.com/beanvalidation/beanvalidation-api/pull/66
