AFAIK the app servers have to provide a way to run with a security 
manager but I don't know how many app server run it by default.

The System.exit example is a good example that has come up a few times. 
There is at least one IDE that used to run with a SM so that it could 
block plugins from calling System.exit. That use case is one that 
probably needs a specific API.
