Unable to close store neostore.nodestore.db - neo4j

Question

I've got a problem starting my Neo4J 2.0.0-M05 embedded instance with an empty graph.db folder.
If i try to do I get the following exception:

I'm using Windows 7 as host system and Java 1.7.40. I checked if there is a process locking the graph.db folder or whatever, but like Process Explorer says, everything is fine.
Yesterday i was able to start the embedded database and fill it with my migration script, but i used Neo4J 2.0.0M-04 at this time.
Is this probably a bug in the latest release or what can i do to avoid it?
Best regards;
