> It throws:

> 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.
