Hi,
It is likely to be related to how you initialize Solr & create your
SolrCore; there has been a few changes to ensure there is always a
CoreContainer created which (as its name stands), holds a reference to all
created SolrCore.
There is a CoreContainer.Initializer class that allows to easily create that
CoreContainer (even if you don't have a solr.xml).
Hope this helps,
Henri
