Answer 1

I think it is because you have 2 different version of com.sun.jersey in your pom.xml. Try to remove below one as 1.17 version of different jersey library is present in the pom file and there may be chances of mismatch of version.
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-servlet</artifactId>
<version>${project.version}</version>
</dependency>
