Illia Khokholkov created JCR-3981:
-------------------------------------
Summary: Null pointer exception on journal synchronization
Key: JCR-3981
URL: https://issues.apache.org/jira/browse/JCR-3981
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: jackrabbit-core
Affects Versions: 2.11.3
Reporter: Illia Khokholkov
Using Jackrabbit 2.x, I am experiencing an issue that is similar if not
identical to the JCR-773, which was "remedied" a long time. The stack trace of
an exception looks like this:

Unfortunately, I cannot determine the root cause of the problem yet, because it
appears to be sporadic. However, when it happens, none of the cluster members
can ever get back to normal.
*Questions*
As pointed out before, the JCR-773 is marked as fixed so I assume there should
be no errors like the ones I see. Anyway, it would be great if I could get an
answer to the following question:
* Is this a known problem and if so, how can it be mitigated/eliminated?
