Hi Sebb,

Right now I have both of these packages:

- org.apache.commons.lang3.annotation.concurrent.clazz
- org.apache.commons.lang3.annotation.concurrent.runtime

Each with a copy of:

GuardedBy
Immutable
NotThreadSafe
ThreadSafe

Should we include what I have as is?

If we were to only provide the annotation at the CLASS retention level,
should we still package them in ...annotation.concurrent.clazz in case we
want to provide annotation.concurrent.runtime later?

If we know for certain we never want to provide RUNTIME retention, we can
put them all in annotation.concurrent now.

Thoughts?

Gary
