[jira] [Commented] (LOG4J2-1617) PatternLayout Exception handling with filter

["Thomas Deutsch (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LOG4J2-1617?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16685765#comment-16685765 ] 

Thomas Deutsch commented on LOG4J2-1617:
----------------------------------------

I just want to note that i had a similar issue. I wanted to configure some sub parameters using  `%xEx` and i think there is a problem combining more than one param. 

This is working: `%xEx\{filters(${exfilters})}` (substitution works!)

but if i add another option like `separator` it stops working. 

I checked version 2.8.1 and 2.9.1 

thank you for your great work!

> I am using log4j2 with this 2 dependencies:
>     <dependency>
>         <groupId>org.apache.logging.log4j</groupId>
>         <artifactId>log4j-core</artifactId>
>         <version>2.6.2</version>
>     </dependency>
>     <dependency>
>         <groupId>org.apache.logging.log4j</groupId>
>         <artifactId>log4j-1.2-api</artifactId>
>         <version>2.6.2</version>
>     </dependency>
> When I try to log for example an error with a throwable like:
> import org.apache.logging.log4j.LogManager;
> import org.apache.logging.log4j.Logger;
> import org.testng.annotations.Test;
> public class Test {
> private static final Logger logger = LogManager.getLogger(Test.class);
> @Test
> public void testSendMessage() throws Exception {
>     Exception exception = new Exception("some exception");
>     logger.error("error with exception", exception);
> }
> }
> using patternlayout:
> <Configuration>
> <properties>
>     <property name="filters">org.testng,org.apache.maven,sun.reflect,java.lang.reflect</property>
> </properties>
> <Appenders>
> <Console name="ConsoleAppender" target="SYSTEM_OUT" direct="true">
>             <PatternLayout pattern="%maxLen{%d{DEFAULT} [%p]  %c{-3}:%L - %enc{%m} %xEx{filters(${filters})}%n}{200}"/>
>         </Console>
> </Appenders>
> <Loggers>
>     <logger name="my.test.class.path" level="trace" additivity="false">
>         <AppenderRef ref="ConsoleAppender" />
>     </logger>
> </Loggers>
> </Configuration>
> Then the filtered packages won't disappear from the stacktrace, I can't even manipulate the stacktrace in any way like maximizing the lines:
> %xEx{5}
