Hi Kevin, support for Jena SDB has been introduced with TBC 3.1. From what I have heard SDB is generally strongly recommended over Jena DB.
TDB has left alpha stage recently and will be more prominent with TBC 3.2 Thanks for the stack trace, which only concerns Jena DB support, which has been removed from our code base already for 3.2.
