   @dlg99 `-Dnetworkaddress.cache.ttl` cannot be passed as system property from 
CLI but rather included in `java.security` property file. 
   
   In any case, the current behavior is caching the DNS resolution forever in 
the BK client process. That comes before reaching the JVM DNS cache or the OS 
DNS cache. By creating new instances of `InetSocketAddress` we will rely on the 
JVM cache, that depends on the `networkaddress.cache.ttl` setting. 
   
   (BTW: I think the JVM cache is a *bad* thing on its own, but that's a 
different story... :) )

 Review comment:
   How should be pass it? 
   
   What I wanted to achieve here is: 
* Try to shutdown bookie gracefully (mainly to close ZK session such that 
new ledgers won't choose this bookie)
* No matter what, bring the process down after that attempt. This would 
protect from a thread hanging on in background to keep JVM alive.

 Review comment:
   Don't call this directly here.  Bookie is used in all tests, and halt 
getting called in the middle of a test is a pain to track down (especially 
since in OOM scenario, the LOG may fail).

 Review comment:
   If you're correcting the grammar, you should at least include the indefinite 
article ;)
   
   Let's see if this suggestion thing works...
   
   ```suggestion
   log.error("Sse42Crc32C is not supported, will use a slower 
CRC32C implementation.");
