Hi, It depends of the import range mostly.
I would say that most of user scoped applications should run smoothly on 4.2.x and 4.3.x if the import version ranges are large enough. In your case, it seems you are registering the same servlet two times with different alias. I have to check in Pax Web 7.3.x if we added some "checks" there. However, it sounds like a fix in 4.3.x, and you "used" the bug in 4.2.x by dual registration.
