[jira] Resolved: (JCR-831) NPE Exception Thrown By AbstractJournal
During Commit Operation
Posted by "Dominique Pfister (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/JCR-831?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dominique Pfister resolved JCR-831.
-----------------------------------
Resolution: Fixed
This bug should have been fixed by the refactoring that took place while working on JCR-757: this version of AbstractJournal still relied on an instance variable named "out" that may or (in exceptional cases) may not have been initialized in the updateCreated/updatePrepared callback methods. While I could see myself these errors now and then in the non-refactored version, they disappeared after the resolving of JCR-757, which didn't make it into the 1.2.3 release, though.
