Howard M. Lewis Ship closed TAP5-1665.
--------------------------------------

       Resolution: Fixed
    Fix Version/s: 5.3

Tapestry now generates a reusable "plan" for invoking constructors or service builder methods, and will retain that plan for scopes other than the default "singleton" scope. This skips a large amount of repeated analysis of fields and public methods and constructor/method arguments.

It does introduce a tiny change in semantics, in that an @Autobuild parameter to a service will be cached and reused, rather than recreated on each construction.

> For services that may be created again on each request, Tapestry does a lot of extra work to analyze the class, constructor and fields. It should be able to roll up all this information into a repeatable "plan" that can simply be re-executed on each subsequent instance creation.
