-----------------------------
Summary: NPE in LuceneMessageSearchIndex for MailboxEvents.Added
while running imapsync
Key: JAMES-3915
URL: https://issues.apache.org/jira/browse/JAMES-3915
Project: James Server
Issue Type: Bug
Affects Versions: 3.9.0
Environment: Ran in docker container
Reporter: Wojtek
While running imapsync, we encountered error
{{o.a.j.e.d.EventDelivery$Retryer$BackoffRetryer - listener
org.apache.james.mailbox.lucene.search.LuceneMessageSearchIndex exceeded
maximum retry(8) to handle event org.apache.james.mailbox.even
ts.MailboxEvents.Added}}
There doesn't seem to be more information (i.e. which email triggered the
issue). From the cursory check it seems that the message that would be added to
the index is probably "faulty" so the header can't be properly parsed (?!)
resulting in null.
There is another tiny nuisance - before this finall exception/stacktrace, there
are repeated "plain" stacktrace (I would guess the retries yielding the failure
at retry) - is there a way to avoid the retry NPEs being logged and only
leaving the final one (with retry failure)?
Stacktrace (final entry):
{{21:45:28.406 [ERROR] o.a.j.e.d.EventDelivery$Retryer$BackoffRetryer -
listener org.apache.james.mailbox.lucene.search.LuceneMessageSearchIndex
