Subject [jira] [Commented] (LOG4J2-245) EmptyStackException when logging exceptions with Log4J2 in Java 8
Date Wed, 20 Nov 2013 10:24:36 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-245?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13827516#comment-13827516
] 

Max Larson commented on LOG4J2-245:
-----------------------------------

I have the same problem under a different environment. I'm using a Mac with JDK 1.7.0_45 (Oracle),
which shows the same behavior as describe here, except that the issue still exist in the 2.0-beta9.

Some background information we used Java 6 and log4j 2.0-beta4 and migrated over to Java 7
and stumbled over this issue. After reading through all the related information about this
issues, we updated log4j to 2.0-beat9. Still the issue is existent. I cannot say for sure
if it is the same cause as described here, but as long i can judge i would yes. That's why
i comment here and doesn't open a new issue. BTW using again Java 6 doesn't expose this behavior.

> [Note: the description below is the original error report. After analysis it turned out
that this problem will happen unconditionally when logging a Throwable on a Java 8 JVM.]
> Possibly affects earlier versions, too, but I did not check.
> beta5 and beta6 are both unusable with Spring Framework. Any time an error gets logged
through log4j-jcl bridge using Spring, the error below appears in the Tomcat log, masking
the error that Spring was trying to log and making it very difficult to figure out what happened.
I've also included my configuration file below the stack trace. The root error is happening
on Tomcat 6 due to Spring bug, and that root problem is unimportant. The important problem
is the Log4j error that masks it.
