RuntimeAnnotation class is needed

[scabug]

There should be a RuntimeAnnotation class which would allow new annotations with RetentionPolicy.RUNTIME to be created in Scala. Currently, these have to be written in Java and compiled in a separate step.

What is the status of this ticket? Missing support for runtime retention can be a severe blocker for Scala adoption in companies. Needing to use Java sources for annotations makes it difficult to convince sceptics of Scala. Please consider adding it in the near future.

Also what are the challenges in the implementation? If this would be trivial to implement, it would probably already be available.

I just noticed that this bug has a Fix Version of 2.11.0-M3. Is that accurate? If so that would be terrific.

I'm afraid it looks like that was a glitch in a batch change. We're not currently planning to do this.

As documented in the discussion linked above, this is a tough nut to crack. Contributions welcome. Alternatively, please contact Typesafe for commercial support.

I'm not sure if "won't fix" is the correct resolution for this then ("community", "grand-challenge").

Also related to #7041 and the discussion in scala/scala#1924. I'm actually not at all convinced that "RuntimeAnnotation class is needed".
