Tomás Fernández Löbbe updated SOLR-3477:
----------------------------------------
Attachment: SOLR-3477-3_6.patch
SOLR-3477.patch
I checked this and saw the same as Tommaso, it seems to work on trunk and 4x
branch.
I added a test case that start the CoreContainer with no cores (a solr.xml file
with an empty list of cores). It works on trunk and fails on 3.6 with an
exception as the one described in the description of this issue.

> Since version 3.6.0, Solr does not start up when no cores are defined in
> solr.xml. The problematic code is in CoresContainer.java, lines 171-173.

> In our case, this is however a valid situation, because we create the cores
> programatically by calling the webservices to register new cores. The server
> is initially started with no cores defined, and depending on the
> configuration of our application, cores are then created dynamically.
> For the time being, we have to stick with version 3.5, which did not have
> this problem (or feature).
