createHotRodServers() from org.infinispan.client.hotrod.test.MultiHotRodServersTest crashes when using replication queue

When a class extends MultiHotRodServersTest and tries to use createHotRodServers to create 2 servers with REPL_ASYNC and useReplQueue configurations, it crashes on the error message "Use of the replication queue is only allowed with an ASYNCHRONOUS cluster mode."

Configuration config = new Configuration().fluent()
               .clustering()
                  .mode(CacheMode.REPL_ASYNC)
                  .async()
                     .replQueueInterval(1000L)
                     .useReplQueue(true)
               .eviction()
                  .maxEntries(3)
               .build();      
createHotRodServers(2, config);

I think this happens because in HotRodServer in method createTopologyCacheConfig REPL_SYNC is set but replication queue is not disabled.
