Erick Erickson updated SOLR-5466:
---------------------------------

    Attachment: SOLR-5466.patch

Updated patch that resolves some merge conflicts against trunk.

I noticed that, while the test succeeds, it always throws this exception both from a terminal
and in IntelliJ, is there a way we can clean this up?

> The collections API lets you add, delete and modify existing collections. At the moment
the API does not let you get a list of current collections or view information about a specific
collection.
> The workaround is the use the Zookeeper API to get the list. This makes the Collections
API harder to work with. 
> Adding an action=LIST would significantly improve the function of this API.
