J=C3=B6rg Hoh created OAK-5216:
-----------------------------

             Summary: AsyncIndexUpdate: CONCURRENT_UPDATE should contain re=
levant stacktrace
                 Key: OAK-5216
                 URL: https://issues.apache.org/jira/browse/OAK-5216
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: lucene
    Affects Versions: 1.0.33
            Reporter: J=C3=B6rg Hoh
            Priority: Minor


We are currently investigating problems regarding a failing AsyncIndexUpdat=
e. The first error message starts like this:

{noformat}

at that time the application was already running for some hours, this did n=
ot happen on startup!

Also the code indicates, that the exception itself is created on creation o=
f the AsyncIndexUpdate service, so the stacktrace does not give any insight=
 under which condition the exception occurred at all. This should be change=
d in a way, that the stacktrace contains relevant information about the roo=
t cause of the exception.
