It is a design feature of servlet sessions that if you open the same application in multiple windows in the same browser type, the session data is shared across them all. This post on Stack Overflow discusses the issue.
Therefore, if for example you need multiple sessions present in order to test Optimistic Lock collisions, you need a way around this. There are 2 solutions :-
- Use a different browser type in each window. For example, if you use Firefox and Chrome as a pair, or Firefox and Opera for example, you will in fact get separate sessions as there is no sharing of cookies and other related data across different browser types.
- Log in from another computer, for example by using an RDP session to another computer on the same desktop and running the application from there. In this case, both browser types can be the same.
