Multiple ListAppenders in YAML config
Hi,
I am preparing a pull request for LOG4J2-2403 and modified an existing
Unit-Test that has its configuration in YAML format. I added a second
ListAppender, but this causes the Unit test to behave strangely.
It seems that, since I have two ListAppenders now, the sequence numbers are
shared between the Appenders. So one of them gets the sequence number 1, 3,
5, 7, 9 and the other gets 2, 4, 6, 8, 10. Is there a way to avoid this?
The seconds problem is that the sequence number is not reset between the
tests. I do not know how to do this with the LoggerContextRule.
The Unit-Test I have modified is SequenceNumberPatternConverterTest.
Please find attached the modified Test class and its corresponding YAML-File.
Any suggestions on how to solve these problems? I could create a seconds
Unit test class, but I would rather use the same because they actually test
exactly the same functionality, only with different patterns.
Best regards
Marco

Well,
I have now split those tests into two separate Test classes.
I have prepared a pull request for it. It would be great if someone reviews
it and include it in the next release of Log4j2.
JIRA Ticket: https://issues.apache.org/jira/browse/LOG4J2-2403
Pull Request: https://github.com/apache/logging-log4j2/pull/224
Best regards
Marco
