[jira] [Updated] (LOG4J2-684) ConsoleAppender does not print
suppressed exceptions
[ https://issues.apache.org/jira/browse/LOG4J2-684?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Attachment: LOG4J2-684.zip
Hi Gary,
here is a Gradle project that demonstrates what I'm seeing.
You can either run the test case with "./gradlew run" or import this project into Eclipse (use STS + Gradle plugin to be up and running quickly).
It's using SLF4J 1.7.7 and Log4j2 2.2.
The main class shows the difference in output between a "printStackTrace" invoked on the exception and the output of the same exception logging.

> (Actual version was 2.0-rc2 but that wasn't available in the list.)
> Currently, any potentially available suppressed exceptions are ignored by ConsoleAppender.
> Instead, it should print those exceptions with the prefix "Suppressed: ". Be aware that suppressed exceptions are indented with a \t, recursively, in contrast to the way "Caused by: " is handled.
> See Throwable.printStackTrace of Java 7 or higher for the implementation.
> Feel free to use the code over at https://github.com/huxi/lilith/blob/master/lilith-data/logging/src/main/java/de/huxhorn/lilith/data/logging/ThrowableInfo.java if it helps.
