Subject Re: ).Re: Add property to Route (not Exchange)

I do not use OSGI unfortunately.

The other possibility you describe is more or less exactly what I already
created as a work-around. The main downside to it is that I have to manage
the lifecycle of those properties separately from the Routes themselves
rather than being all bundled together.
