It is one of the three mechanisms by which ...
As shown in the figure, at the root of the processes is the main WAS bootstrap process: a Java JVM machine by itself, that is started first then followed by multiple JVM processes that are spawned underneath it, each of which represents an enterprise application with its own classloader.
