Bitarchive - spurious java.sql.SQLNonTransientConnectionException / java.lang.ArrayIndexOutOfBoundsException

While running the TEST11B I was browsing the Firestatus and at one point moving back in the browser history I got this exception. I have not been able to reproduce it yet.

SQL error executing statement org.apache.derby.client.am.PreparedStatement40@9f5742
