Subject [jira] [Created] (OAK-8328) Bug in index definition can block indexing / cause indexing in a loop
Date Fri, 17 May 2019 07:29:00 GMT
Nitin Gupta created OAK-8328:
--------------------------------

             Summary: Bug in index definition can block indexing / cause indexing in a loop
                 Key: OAK-8328
                 URL: https://issues.apache.org/jira/browse/OAK-8328
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: core, lucene
            Reporter: Nitin Gupta


If we  set "/oak:index/indexName/entryCount" to a Long multi-valued property. That will cause
the system to reindex in a loop... You only see the root cause if debug level logging is enabled.
There are likely other such problems. Oak should log a proper meaningful exception for config
errors, and if possible not get into this loop. It also blocks other indexes to be updated
I think.
