--------------------------------------------------------------

[~dmlloyd] priority annotation from Common Annotations 1.3 gained [*PARAMETER* applicability level|https://github.com/javaee/javax.annotation/blob/master/src/main/java/javax/annotation/Priority.java#L66], not METHOD.
See also chapter 2.7 in [spec|http://download.oracle.com/otndocs/jcp/common_annotations-1_3-mrel3-spec/].

Which means that this issue isn't really relevant for interceptors. Those are, at least in CDI, still sorted based on class-level priority annotation.
What we use this param-level annotation for in CDI/Weld is observer ordering. As can be seen in [this|https://github.com/cdi-spec/cdi-tck/blob/master/impl/src/main/java/org/jboss/cdi/tck/tests/event/observer/priority/MoonObservers.java#L40] or [this|https://github.com/cdi-spec/cdi-tck/blob/master/impl/src/main/java/org/jboss/cdi/tck/tests/event/observer/priority/MoonObservers.java#L40] test.

> The {{@Priority}} annotation in Common Annotations 1.3 has gained a METHOD applicability level.  We must ensure that our interceptor metadata processing picks up these annotations.
