16.11. Create an Execution Context

As mentioned above, the starting point is to create a default execution context, which will have all the default components:

ExecutionContext context = new ExecutionContext();

ExecutionContext context = new ExecutionContext();

Once you have this top-level context, you can start creating subcontexts with different components, and different security contexts. (Of course, you can create a subcontext from any ExecutionContext instance.) To create a subcontext, use one of the with(...) methods on the parent context. We'll show examples later on in this chapter.
