11.6.4. - There is a stray step "4" with no instructions. Step 4 should be to compile the output from step 3 with your application to use those objects.

Chapter 29 - Replace all occurrences of NotifyingFuture with CompletableFuture

30.4.3.1. - "allMatch
This operator is ran on each node" -> "run on each node"

30.4.3.2. - "iterator spliterator
These operators will return back sets of batches worth of entries when ran on a remote node, where the next batch is only sent after the previous is fully consumed." -> "These operators return batches of entries when run on a remote node, where the next batch is only sent after the previous is fully consumed."

34. - "Cross-Datacenter Replication ensures data redundancy across clusters. Ideally, each of these clusters must be in a different physical location than the others." -> "Cross-Datacenter Replication ensures data redundancy across clusters. Ideally, each of these clusters should be in a different physical location than the others."

34.3. - This section is a little strange, because it talks about the various ways that a site can be taken offline and only shows the programmatic example.

34.4. - "Manual Cross Site Cluster Failover

For manual site cluster switchover, call RemoteCacheManager’s switchToCluster(clusterName) or switchToDefaultCluster().

Using switchToCluster(clusterName), users can force a client to switch to one of the clusters pre-defined in the Hot Rod client configuration. To switch to the initial servers defined in the client configuration, call switchToDefaultCluster()." - The second paragraph seems to refer to pre-defined clusters in the server configuration? (Maybe I'm wrong about this, but it isn't clear which client configuration it is referring to.

35.1. - The warning should also say eager near caching is deprecated. (https://issues.jboss.org/browse/ISPN-5544)

35.3. - This section seems redundant, since this information is provided in the Note above about setting the size of the near cache

36. - This chapter is completely malformed in my version and has not been reviewed. It should also be placed before the Appendix. I reloaded the Developer Guide, and this chapter is gone.
