             Summary: Starting a plain Hot Rod server requires fiddling with default cache
                 Key: ISPN-8826
                 URL: https://issues.jboss.org/browse/ISPN-8826
             Project: Infinispan
          Issue Type: Bug
          Components: Server
    Affects Versions: 9.1.6.Final, 9.2.0.CR2
            Reporter: Galder Zamarreño


The following code does not work:

{code}
final DefaultCacheManager cacheManager = new DefaultCacheManager();
final HotRodServer server = new HotRodServer();
server.start(new HotRodServerConfigurationBuilder().build(), cacheManager);
{code}

It throws:

{code}
org.infinispan.commons.CacheConfigurationException: ISPN000433: 
A default cache has been requested, but no cache has been set as default for this container

{code}

The Hot Rod server should not have to care about the default cache. In the past, calling getCache on default cache used to be make sure the node starts up components such as JGroups...etc.

This shouldn't be necessary, but needs double check with [~dan.berindei] and also [~pferraro] for repercussions of changes at this level.
