[Hawkular-dev] possible bug in inventory server

[Joel Takvorian]

Some update, here is the latest logs I got while the test failed:

I haven't time to dig further today, but see in the middle that lovely
stack trace:

*18:01:59,012 ERROR

ISPN000255: Error while processing prepare:

I have no idea why it wasn't displayed before, and it is now.
