After this Future succeeds, runs your function on the async executor and returns a new Future with the transformed value.
Description
thenApplyAsync runs the callback on a worker thread from the ColdFusion async pool. The callback receives the successful result of the previous stage and must return the next value. ColdFusion preserves variable scope so closures can read
variables and other scopes as in your tests.Returns
A new Future.
