[jboss-as7-dev] multiple instances of AS per VM?

[Scott Marlow]

Do we have any use cases where we need to support multiple instances of 
the AS per VM?  I heard that this was part of the early design but 
doesn't seem to be taken advantage of, as far as I know.

In my changes for AS7-2076 (serialization of extended persistence 
context), I used a class variable, which would be shared between the 
multiple AS instances (if I don't change it).  I could switch to using a 
service and lookup the service through 
CurrentServiceContainer.getServiceContainer().getService() but that also 
uses a class variable for tracking the current AS.  The advantage of 
using CurrentServiceContainer.getServiceContainer(), is better 
encapsulation of code that needs to change, if we do run multiple AS 
instance per VM at some point.
