>
> We are unclear about the behavior of HSQL-based recovery log when handling 
> requests involving BLOBs. This has not been sufficiently tested.
> In particular, we perform SELECT request on tables which contain BLOBs, which 
> is not recommended, see:
> http://www.hsqldb.org/doc/guide/ch02.html#N1047A (Storage and Handling of 
> Java Objects)
> This has prevented proper transaction clean-up after failure, the 
> ControllerFailureCleanupThread blocked while checking if a BEGIN had been 
> logged for a given transaction.
