JiraHomeAppender/FileAppender not working as expected in Jira 9.5

[Trishia Mae Gumboc]

• JiraHomeAppender - throws an IllegalAccessError when used in Jira 9.5.

Code Snippet:

import org.apache.log4j.Level;
import org.apache.log4j.Logger;
import org.apache.log4j.PatternLayout;
import com.atlassian.jira.logging.JiraHomeAppender;

......

private final Logger rootLogger = Logger.getRootLogger();

.....

private void initLogger() {
   JiraHomeAppender jiraHomeAppender = new JiraHomeAppender();
   jiraHomeAppender.setName(Constants.LOGGING_NAME);
   jiraHomeAppender.setFile("test.log");
   jiraHomeAppender.setLayout(new PatternLayout("%d %-5p [%c{1}] %m%n"));
   jiraHomeAppender.setThreshold(Level.INFO);
   jiraHomeAppender.setAppend(true);
   jiraHomeAppender.activateOptions();

   rootLogger.addAppender(jiraHomeAppender);
   rootLogger.getLoggerRepository()
             .getLogger(Constants.LOGGING_NAME).setLevel(Level.INFO);
}

Error:

• FileAppender/RollingFileAppender - I used this as an alternative fix for the JiraHomeAppender issue. The error doesn't occur, and custom log file has been created, but the problem is that there are no logs being printed in the file in Jira 9.5, but working as expected in lower versions. Is there something that I need to add to this configuration?

Code Snippet:

import org.apache.log4j.Level;
import org.apache.log4j.Logger;
import org.apache.log4j.PatternLayout;
import org.apache.log4j.FileAppender;
........

private final Logger rootLogger = Logger.getRootLogger();
........

private void initLogger() { 
    FileAppender fileAppender = new FileAppender();
    fileAppender.setName(Constants.LOGGING_NAME);
    fileAppender.setFile("jira/home/test.log");
    fileAppender.setLayout(new PatternLayout("%d %-5p [%c\{1}] %m%n"));
    fileAppender.setThreshold(Level.INFO);
    fileAppender.activateOptions(); 
 
    rootLogger.addAppender(fileAppender);
    rootLogger.getLoggerRepository()
              .getLogger(Constants.LOGGING_NAME).setLevel(Level.INFO);
}

Do you have any suggestions to resolve this issue?

Thank you.

Hi @Trishia Mae Gumboc 

Welcome to the Community!

Jira 9.5 is the log4j update ( >=2.17.2). Here you can find information about the update.

This might be helpful for your problem. You can also check this article.

I hope you find them helpful.

Hi @Tuncay Senturk

I dont know if i missed something from the details but i haven't seen any details whether if it is backwards compatible with older jira versions? I have already a working fix with jira 9.5 but unfortunately it isn't working with older versions.

Thanks,
fritz

No, it won't be backward compatible. You need to have separate binaries for each (one for < Jira 9.5 and the other for >= Jira 9.5)

If you want to have one binary to have backward compatibility, you must implement a bridge API. Have a look at this post. It may shed a light.
