You are mixing the jersey1 and jersey2 dependencies here. Remove the following one from your pom.xml 

<dependency>
  <groupId>org.glassfish.jersey.bundles</groupId>
  <artifactId>jaxrs-ri</artifactId>
  <version>2.16</version>
</dependency>
<dependency>
  <groupId>org.glassfish.jersey.media</groupId>
  <artifactId>jersey-media-moxy</artifactId>
  <version>2.16</version>
</dependency>

and add below one 

<dependency>
  <groupId>com.sun.jersey</groupId>
  <artifactId>jersey-grizzly2</artifactId>
  <version>1.19.1</version>
</dependency>

If you need json support, then add below one: 

<dependency>
  <groupId>com.sun.jersey</groupId>
  <artifactId>jersey-json</artifactId>
  <version>1.19.1</version>
</dependency>

If possible think to migrate to jersey2 .
