I just hit the same issue with JBoss RestEasy. We have an embedded
server (not EE class, a simple servlet with some web services
exposed), but RestEasy relies on annotations in jaxrs
(javax.annotation.*, javax.ws.rs.*). I tried to somehow make it work,
but failed so far. Please correct me if I'm wrong, but from my
investigation of this list archives it seems that it's impossible to
simply "add" the JAR with the missing annotations to classpath? I need
to compile those annotations to a module and then add the module,
right?

If so then it makes it extra difficult to have an interoperable build
script (and tests) for Java 8 and 9.
