I have found a workaround for this issue. For some reason, the server
seems to depend on the jersey-client package. Edit the pom file and
remove the <scope> line from the jersey-client dependency :
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-client</artifactId>
<scope>test</scope>
</dependency>
This should remove your warnings.
