Hystrix errors with spring singleton beans

[viniciusccarvalho]

Seems that some Oauth beans need to run on the same thread that the caller, this lead to errors bellow. Because methods are ran inside hystrix commands, we don't have access to the original thread.

Need to investigate further:

Error creating bean with name 'scopedTarget.oauth2ClientContext': Scope 'session' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton

java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

Yep, seems to be that OAuthRestemplate tries to access OauthContext (I need to confirm if its the same of SecurityContext from Spring Security). If this was set by a Filter on a ThreadLocal, we won't be able to access it.

Need to figure out a way to store context on session perhaps
