ClassCastExceptions, corrupt index

Deleting the solr index directory followed by "rebuild solr metadata index" seems to work.
BUT: Any changes to the index like update of a single entry VIA CLI will move the index to a broken state, no updates possible afterwards any more.

The log is full of the following exceptions:

auto commit error...:org.apache.solr.common.SolrException: Error opening new searcher

auto commit error...:java.lang.ClassCastException: org.apache.lucene.search.IndexSearcher cannot be cast to org.apache.solr.search.SolrIndexSearcher
