What about to create a "static" field and inject in only once? Maybe after class-load. Usually my domain objects do not get different classes injected. So the restriction that all instances in a JVM can have only the same dependecies injected is no issue for me. What do you think? Greetings, Robert I'm thinking about performance issues when injecting dependencies in each created domain object and how to avoid the repeated overhead.

I did a presentation a year ago on the Jazoon conference talking exactly about problems with DI and domain objects (and serialization). http://jazoon.com/download/presentations/866.pdf It's very good to hear that you've implemented exactly what I was proposing back then.
