Why public Admin findByLoginAndPassword(String login, String password) has limit 2 ?

Hello,

I have a query defined by its method signature in an interface:

public Admin findByLoginAndPassword(String login, String password)

It gives the following sql statement:

select admin0_.id as id14_, admin0_.address as address14_, admin0_.city as city14_, admin0_.country
as country14_, admin0_.email as email14_, admin0_.firstname as firstname14_, admin0_.lastname
as lastname14_, admin0_.login as login14_, admin0_.password as password14_, admin0_.password_salt
as password10_14_, admin0_.post_login_url as post11_14_, admin0_.preference_admin as preference12_14_,
admin0_.profile as profile14_, admin0_.super_admin as super14_14_, admin0_.version as version14_,
admin0_.zip_code as zip16_14_ from admin admin0_ where admin0_.login='stephane' and admin0_.password='toto'
limit 2

I wonder why is there a limit 2 and where it's coming from.

I'm using Hibernate 3.6.9.Final and Spring Data 1.3.0.RELEASE
