[jira] Created: (JCR-2813) "overwriting cached entry" warnings
"overwriting cached entry" warnings
-----------------------------------
Key: JCR-2813
URL: https://issues.apache.org/jira/browse/JCR-2813
Project: Jackrabbit Content Repository
Issue Type: Bug
Reporter: Stefan Guggisberg
Priority: Critical
when using multiple concurrent sessions you'll find *lots* of log entries like:
03.11.2010 21:17:03 *WARN * ItemStateReferenceCache: overwriting cached entry ad79ca57-5eb1-4b7d-a439-a9fd73cc8c5a (ItemStateReferenceCache.java, line 176)
those are actually legitimate warnings since there's a siginificant risk of data loss/inconsistency involved.
this is apparently a regression of changes introduced by JCR-2699, specifically svn r1004223
