[cdi-dev] cdi-dev Digest, Vol 47, Issue 13

Tue Oct 28 07:50:14 EDT 2014

Interestingly there is no @Priority in Java SE 8 see that JavaDoc:
http://docs.oracle.com/javase/8/docs/api/javax/annotation/package-summary.html

Meaning we won't get that one via Java 8 anyway, and it shows, there could
be flexibility to pick just the annotations you need for CDI 2 under the
right circumstances, too[?]
