Conversion from String to Locale not working when using Criteria API with Restriction

I have following table:

That has following contents:

I have following class:

which is mapped to that table as you can see. Fetching the contents of the table works fine:

As a side note, the above code works fine if you have Hibernate 3.5.6-Final.
