Yoav Landman commented on JCR-2239:
-----------------------------------

Well, it is certainly not "minor", since our application is dead once we get this exception...

> This seems to be a similar issue to JCR-2168. This time, it is the ItemManager that is
registered on SessionItemStateManager before its construction completed, resulting in the
following NPE. Once this happens, all transactions are frozen (IIRC, DefaultISMLocking#acquireWriteLock
is blocked, but I lost the original thread-dump).
