BatchInserter initialization yields ArrayIndexOutOfBounds and ExceptionInInitializationError

All I'm trying to do is the following:

    BatchInserter ins = BatchInserters.inserter("target/batchinserter-example");

where "target/batchinserter-example" is a given store directory. It compiles fine, but I get:

Exception in thread "main" java.lang.ExceptionInInitializerError
    at org.neo4j.unsafe.batchinsert.BatchInserterImpl.rejectAutoUpgrade(BatchInserterImpl.java:556)
    at org.neo4j.unsafe.batchinsert.BatchInserterImpl.<init>(BatchInserterImpl.java:219)
    at org.neo4j.unsafe.batchinsert.BatchInserters.inserter(BatchInserters.java:94)
    at org.neo4j.unsafe.batchinsert.BatchInserters.inserter(BatchInserters.java:88)
    at org.neo4j.unsafe.batchinsert.BatchInserters.inserter(BatchInserters.java:63)
    at org.neo4j.unsafe.batchinsert.BatchInserters.inserter(BatchInserters.java:51)
    at NeoBatchInserter.main(NeoBatchInserter.java:26)
Caused by: java.lang.ArrayIndexOutOfBoundsException: 0
    at org.neo4j.graphdb.factory.GraphDatabaseSettings.<clinit>(GraphDatabaseSettings.java:69)
    ... 7 more

I don't understand how this isn't working. I'm literally just calling a constructor that takes a String. I'm quite frustrated at the moment. If there is a better way to do this, I am welcome to trying it. All I want to do is set up a BatchInserter (from scratch) so that I can begin my work.

EDIT: I just attempted to point it a graph.db from a test graph, and this still didn't work...

I'm also using kernel.2.1.3

EDIT 2: Since my server is 2.1.2, I changed my jars to the 2.1.2 version, yet I still get the same error.

What version of Neo4j was the directory created with? I'm pretty sure that you cannot use batchinserter of 2.1.3 with an earlier version.

Install 2.1.3, set allow_store_upgrade=true in neo4j.properties, start the server and shut it down. It's crucial to have a clean shutdown. Then use your batchinserter code.
