Hi, Leonid,
I would classify this as a bug, although I cannot speak for the EMF
Validation project. There were efforts some releases ago to fix
specific concurrency issues (I think I recall something of that nature
in the traversal-strategies, for example). It should, in general, be
possible to work with distinct EMF ResourceSets concurrently, which
implies that components like the validation framework and transactions
should also support this. The transactions explicitly do, and as they
use the validation framework for live validation, that would seem to
require the same of the latter.
Cheers,
Christian
