This is still a work in process.
There are a bunch of TODOs in classes
that are not managed by Spring and so
need to have the MessageBuilderFactory
injected.
But I am looking for feedback on the
approach.
INT-3309 Resolve TODOs
Provide access to the MessageBuilderFactory in all classes.
INT-3309 Polishing + Tests
* Fallback to 'fromMessage()' if mutating and inbound message is not MutableMessage
* Add 'alwaysMutate' boolean to MutableMessageBuilderFactory - coerces 'fromMessage' calls to 'mutateMessage'
* Add tests
INT-3309 Polishing; PR Comments
Also add tests to parent/child contexts where the parent has the
default message builder and the child has a mutable message builder.
INT-3309 More Polish; PR Comments
Also fix removeHeader in MMB.
