Thread implications of IdentityService.setAuthenticatedUser

[tstephen]

Hi,

I've been looking at IdentityService.setAuthenticatedUserId(String) for the first time and wonder how this is intended to be used in a multi-threaded environment?

AFAIK the ProcessEngine is a singleton that returns instances of the various services. Are these instances also singletons? I guess not since using this method would then have side-effects on the other thread(s).

So as long as each thread creates its own identity service all will be well?

Thanks in advance for clarifying

The services are singleton.

The setAuthenticatedUser is using a Threadlocal, which is exactly why it works in a multi threaded environment.
