Description

I'm using a trivial test using SpringJUnit4ClassRunner (RedirectTest.java).

The test prints a simple message to the standard output. I run the test with "mvn test" command.

When log4j is configured to print some spring execution details (logger set to level INFO) the RedirectTest-output.txt file is empty.

To reproduce:
unzip "redirect.zip" file
run "mvn test"
confirm that the file target/surefire-reports/RedirectTest-output.txt is empty

Optionally: edit pom.xml file, change maven-surefire-plugin version to 2.9 .
run "mvn test"
confirm that the file target/surefire-reports/RedirectTest-output.txt is not empty. See attached RedirectTest-output.txt captured using maven-surefire-plugin version 2.9.
