>             Project: Syncope
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 2.0.8
>            Reporter: Isuranga Perera
>            Priority: Major
>             Fix For: 2.0.9, 2.1.0
>
>
> Token create method in AccessTokenDataBinderImpl[1] is not thread safe. This 
> could result in several problems including
>  * Exist 2 different access token for a particular user at a given time which 
> may result in an exception thrown by method call[2] since it expects a single 
> token a given user.
> In addition to that token replace is implemented as a combination of 2 
> different functionalities. Since the method is not thread safe this may cause 
> some unexpected behaviors (since there can be 2 tokens exist for a particular 
> user. same scenario as above).
