[jira] Resolved: (JCR-712) NPE Exception Thrown By FileJournal
During Commit Operation
Posted by "Dominique Pfister (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/JCR-712?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dominique Pfister resolved JCR-712.
-----------------------------------
Resolution: Fixed
Fix Version/s: (was: 1.2.1)
1.2.2
I've noticed this error before refactoring most of FileJournal's code into a base class during resolution of JCR-702. After having refactored and added some more validations in FileRevision, the error did not show up anymore.
Therefore, setting this bug to fixed, with revision 495239.
