Tests in org.infinispan.server.test.client.hotrod can fail due to NPE

Method org.infinispan.server.test.client.hotrod.AbstractRemoteCacheTest#release() annotated with @AfterClass will result in NPE when client tests are run on remote container. It's due to the fact that Arquillian/JUnit runs @BeforeClass and @AfterClass locally, not remotely, see e.g. this thread for details.
