Major Description
I have an Entity with an attribute named "order". While creating the table for the Entity there is thrown an error. Renaming the "order"-attribute fixed this error.
Ill tested this with MySql and H2. With Mysql the "order"-attribute was no problem, h2 thrown that error.
I dont know where the exact problem is, ill hope im right here 
Workarround:
Rename the attribute.
Here the Stacktrace:
