-------------------------------------
Assignee: Viacheslav Kabanovich (was: Alexey Kazakov)
We can't fix this issue without modification of Seam Tools model.
What we can do:
- add new methods to SeamProject like getComponents(boolean createNewCopy); This method
should return new copy of collection. The coping should be thread-safe too.
- use ConcurrentLinkedQueue instead of HashSet in SeamProject. It will allow clients to
work with thread-safe collection of Seam artifacts. We have to figure out if it is fast
enough.
- return Collections.synchronizedSet() in getComponents(). Then every client code should
use sinchronize block when we need to iterate Seam artifacts. Could be slow. Not sure it
is the best solution.
Also we can use CopyOnWriteArraySet in SeamProject but it would be too slow. I don't
think we should use it.
Any ideas?
