manually set MessageHandlerMetadata handledMessages field

[volgar1x]

Hello again

To enable some annotation aliasing I had to specifically say to a given MessageHandlerMetadata what messages has to be handled through a Reflection workaround.

There is maybe a better way to do it but I cannot find it.

Currently, the field is private and setting it using Reflection is thus the only way to go. Changing the constructor could provide more flexibility here but I would need to know more details about your specific scenario. What kind of aliasing are you trying to do?

I changed the way how MessageHandler is constructed. You can now flexibly define all necessary properties in a Map. I think that should solve your problem.
