This was accidentally missed (a bug in v2.0.1). I'll log as a bug and
fix in the next version. As a workaround for the meantime you can use
ServerConfig explicitly.
>> ebean.identityGeneration=identity
In theory you only need this for DB2 or H2 which support both
sequences and identity/autoincrement. You need to explicitly use
ServerConfig and DatabasePlatform to set the identity.
