Manfred Baedke updated OAK-12309:
---------------------------------
Description: This is the root cause of the flaky test OAK-11600. The
activate() method as well as several bind calls touch some non-volatile fields.
Thus it may happen that a bind call falsely assumes that the component is not
activated yet (OAK-11600 is one example). And even if all relevant fields are
made volatile, it still can occur that concurrent threads see all conditions
for NodeStore registration fulfilled simultaneously, leading to a double
registration.
> DocumentNodeStoreService may fail to register or double register the
> NodeStore due to race conditions
