Description

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:
