Hi Leonid,
I also experience this problem recently and I was about to commit a simple fix for it. But then I looked at
CDOLazyContentAdapter a little bit longer and thought it should be reimplemented from scratch without extending
EContentAdapter. If you want me to fix the ConcurrentModificationException separately, please submit a bugzilla and I'll
look at it.
Cheers

That bug is more like an umbrella bug. I've now fixed the ConcurrentModificationException via:
424889: ConcurrentModificationException in CDOLazyContentAdapter
