  | Hmm, i would have expected it to return different instances in the multiple simultaneous requests usecase.

Me too. What I more precisely did was the following simple test:

1) Put the simple above shown code in a ServletFilter I happened to have on my screen that requested the EM out of JNDI.
2) Added a break-point to it, requested a page being filtered, inspected the identity of the instance using the Eclipse debugger.
3) While the request thread was still being suspended, I did a new request (for the same page) in a second tab of the same browser.
4) Observed the break-point was being hit again, but now in another thread and confirmed that the identity of the instance was the same one as was returned for the currently suspended thread.

If there is anything else you'd like me to test, please let me know.
