-----------------------------------
Summary: 2.6.1 - NPE due to OnStartupTriggeringPolicy changes
Key: LOG4J2-1420
URL: https://issues.apache.org/jira/browse/LOG4J2-1420
Project: Log4j 2
Issue Type: Bug
Affects Versions: 2.6.1
Reporter: Leon Finker
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 now set before the
randomAccessFile in RollingRandomAccessFileManager ctor. And the actual policy
triggering happens in RollingFileManager before the randomAccessFile is
assigned:
triggeringPolicy.initialize(this);
The NPE always happens with OnStartupTriggeringPolicy and if previous file is
not empty.
