thanks for the hint. Making it shared sounds a bit fishy to me. My intention is to pass some read only data, that are in fact thread local and there is no real need to make them shared.
The whole point of thread local data is that it's only accessible from a single thread. If you want to share it with another thread you have, as far as I know, there options:
1. Declare it as "shared" 2. Declare it as "immutable" 3. Make a copy, i.e. serialize the data
The (de)serialization is possible but the overhead seems a bit pointless. I will alter the code to use something else than AAs if there is no other way. The data I am trying to pass is in fact just name-value pairs. I have tried to use Tuples, but I have hit another batch of problems. One was related to issue #5783, but another made me really scratch my head...
Looking at your original example I don't understand why the immutable aa won't work. That's the whole point of immutable, it's safe to share among threads. It's probably a bug somewhere. I think someone else can answer these questions better than me.
