What is in the log before that stackdump?

The stackdump seems to indicate that Solr is trying to run with a 
managed schema. Looking at the cwiki, "When a |<schemaFactory/>|is not 
explicitly declared in a |solrconfig.xml|file, Solr implicitly uses 
a|ManagedIndexSchemaFactory|, which is by default|"mutable"|and keeps 
schema information in a |managed-schema|file."*. So your schema.xml 
would be ignored.

Have you tried using a solrconfig.xml copied from one of the examples, 
perhaps with minor changes?
