             Summary: Camel container is too long to start
                 Key: JAMES-2448
                 URL: https://issues.apache.org/jira/browse/JAMES-2448
             Project: James Server
          Issue Type: Improvement
          Components: JMAP, SpoolManager & Processors, tests
            Reporter: Tellier Benoit
            Assignee: Antoine Duprat


A classic mailet container takes up to 1 s to load on a warm JVM.

Fast startup is critical for our testing strategy (relying heavily on 
integration tests). We should make camel container loading faster.

Ideas:

 - Some parameters are passed to components via dynamically generated 
properties, on a per call basis. This is inefficient and can be passed by a 
constructor.
 - Many classes used in CamelMailetContainer are not static
 - We finally can heavily simplify the logic expressed in Camel DSL, and 
express it through a *split - process* way, instead of relying on *camel 
choices*.

We should measure the effect on boot time, and run Gatling SMTP test to 
evaluate the impact on delivery.
