问题
I am getting the following exception on starting up baasbox (it has embedded orientdb).
This exception happens when I connect to the database using console.sh/connect:plocal and then run a few select queries, but doesn't happen the first time I startup baasbox.
Any help is appreciated. Orientdb version: 1.7.10

I got this reply from the baasbox team:
When you use console.sh (the OrientDB console tool), be sure the BaasBox is not running, otherwise you can have data corruption.
However now it is clear that the error occurs after you have accessed the db via the console using a different version of the ODB tool.
I was using a different version of Orientdb tool (console.sh v2.0) than the orientdb version 1.7.10 used in baasbox. This caused the corruption and may have messed up the DB schema.
