[jira] [Updated] (LOG4J2-1420) 2.6.1 - NPE due to
OnStartupTriggeringPolicy changes
[ https://issues.apache.org/jira/browse/LOG4J2-1420?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Leon Finker updated LOG4J2-1420:
--------------------------------
Description:
Hi,
Noticed an NPE with one of our configurations with 2.6.1 (doesn't happen on previous versions). Looks like it's due to changes for LOG4J2-1405. Looks like the file size in RollingFileManager constructor is set before the randomAccessFile in RollingRandomAccessFileManager ctor. And the actual policy triggering happens in RollingFileManager before the randomAccessFile is assigned:triggeringPolicy.initialize(this); I guess that's why there was somewhat an elaborate logic in previous version of OnStartupTriggeringPolicy and the actual rollover was decided in isTriggeringEvent.
The NPE always happens with OnStartupTriggeringPolicy and if previous file is not empty.
