Rupert Westenthaler commented on STANBOL-811:
---------------------------------------------
The problem was that the TopicClassificationEngine was also creating an
embedded Solr server for performing CVFold. This core was still created within
a temp folder (if no EmbeddedSolrServer was present).
With revision http://svn.apache.org/r1450615 I changed this to be manually
configured during unit tests. However the current fix might have an impact with
running within OSGI and no EmbeddedSolrServer is bound to the
TopicClassificationEngine (as this service is configured as optionally).
