             Summary: PatternLayout Exception handling with filter
                 Key: LOG4J2-1617
                 URL: https://issues.apache.org/jira/browse/LOG4J2-1617
             Project: Log4j 2
          Issue Type: Bug
          Components: Layouts, Pattern Converters
    Affects Versions: 2.6.2
         Environment: Eclipse mars 4.5.2
jdk 1.8.77
mvn 3.2.1
testng 6.9.10
            Reporter: Zoltán Nébli


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}

Output:
