Jersey missing explicit dependency on javax.annotation

[cowwoc]

When using Jersey client under Java 9 I get:

java.lang.NoClassDefFoundError: javax/annotation/Priority
	at org.glassfish.jersey.model.internal.RankedProvider.computeRank(RankedProvider.java:111)
	at org.glassfish.jersey.model.internal.RankedProvider.<init>(RankedProvider.java:72)

	at org.glassfish.jersey.client.JerseyInvocation$Builder.post(JerseyInvocation.java:351)

My dependencies are:

		<dependency>
			<groupId>org.glassfish.jersey.core</groupId>
			<artifactId>jersey-client</artifactId>
			<version>2.26</version>
		</dependency>
		<dependency>
			<groupId>org.glassfish.jersey.inject</groupId>
			<artifactId>jersey-hk2</artifactId>
			<version>2.26</version>
		</dependency>
		<dependency>
			<groupId>org.glassfish.jersey.media</groupId>
			<artifactId>jersey-media-json-jackson</artifactId>
			<version>2.26</version>
		</dependency>
		<dependency>
			<groupId>org.glassfish.jersey.connectors</groupId>
			<artifactId>jersey-jetty-connector</artifactId>
			<version>2.26</version>
		</dependency>

Jersey should depend on javax.annotation instead of assuming it will be provided.

See https://github.com/jersey/jersey/issues/3712 for a related discussion.

I think that adding this dependency will lead to many problems for JDK8 users. Why don't you just add this dependency to your pom?

@chkal I tried but never did manage to get this working. If Jersey 2.26 is usable on JDK 9 and 10, the steps should be documented somewhere. I suspect some actual code changes will be required, aside from documentation.

AFAIK the Java EE related packages aren't visible to your application by default. Perhaps you could have a look here to see if this helps:
