[jira] [Updated] (LOG4J2-2324) PatternLayout handling of Throwable alternate separator doesn't accept special characters?

["Robert Ross (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/LOG4J2-2324?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Robert Ross updated LOG4J2-2324:
--------------------------------
    Description: 
When attempting to use an alternate line separator for Throwable stack lines, it seems impossible to use special characters like {{\t \r \n}} or anything else.  It also seems impossible to use variable references so one cannot use ${sys:line.separator} as well as other characters.

In the case of simple uses of {{\t \r \n}} or anything else are converted to plain text, actually resulting in "\t" in the output.
{code:xml}
%-5level - %d{yyyy.MM.dd hh:mm:ss zzz} [%t @ %logger{1}] - %msg%n%ex{separator(\r\n\t)}%n
{code}
 If there's a way to do this, it isn't clear in the documentation.
