[midPoint] Error with inbound mapping in latest build.

Hi Karatina / Ivan -
Many thanks for taking the time to look at this issue despite your busy
schedule.
I worked on it a bit more this weekend and I have managed to "avoid" the
error - rather than figure out the root cause and I think I have to
stick with this for now in order to proceed with what I was originally
doing.
It turns out that on my local environment (where this problem occurs) I
was using a 3.1-SNAPSHOT build of Midpoint against a 3.0 repository. I
am not sure what the consequences of this are (or whether the schema for
MySQL had any changes since 3.0 was released). But I did notice that
once I commented out the mapping below, other errors started appearing
(and strange exceptions such as "clob property type not supported for
...RRole" or something like that).
So I reverted to a 3.0 build, reset my repository, redeployed everything
from scratch from a clean slate, and the error vanished (I wanted to try
this as a last resort).
Thank you!
