Xavier Dury commented on SUREFIRE-1659:
---------------------------------------

I have the same problem with slf4j/logback:

{code:xml}
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M5</version>
    <configuration>
        <systemPropertyVariables>
            <java.util.logging.config.file>${project.basedir}/src/test/resources/logging.properties</java.util.logging.config.file>
        </systemPropertyVariables>
    </configuration>
</plugin>
{code}

with {{src/test/resources/logging.properties}} containing:

{code}
handlers = org.slf4j.bridge.SLF4JBridgeHandler
{code}

> I have a project that registers a JUnit 5 TestExecutionListener. The TestExecutionListener contains an SLF4j Logger, using Log4j2 as the underlying library. There is a log4j2.xml on the classpath, logging to console, and Surefire is set up to redirect output.
> Running the tests gives the following result.
> {quote}
> [WARNING] Corrupted STDOUT by directly writing to native stream in forked JVM 1. See FAQ web page and the dump file ...
> {quote}
> I've attached a minimal reproduction.
> Doing either of the following eliminates the error:
> * Not having the log4j2.xml on the classpath
> * Not having the Logger in the TestExecutionListener
