JaCoCo stopped working after setting the log4j.configurationFactory system property.

Exception in thread "main" 

I've read about an error like that with JaCoCo and JDK 1.8, but it was already solved in JaCoCo 0.7.7.

The VM arguments are defined like following:

-Dlog4j.configurationFactory=mytest.CustomConfigurationFactory
-Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager
-Dcom.sun.management.jmxremote.rmi.port=9090
-Dcom.sun.management.jmxremote=true
-Dcom.sun.management.jmxremote.port=9090
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.local.only=false
-Djava.rmi.server.hostname=localhost
-javaagent:/path/jacocoagent.jar=destfile=C:/TEMP/jacoco.exec,jmx=true

I'm using:

  • JaCoCo 0.7.7
  • Log4j 2.8.1
  • JDK 1.8.0_102

Does anyone know how to solve it?

As was answered in JaCoCo users mailing list :

There seems to be a real problem in interactions between JaCoCo (up to the latest version that is 0.7.9 as of today), JMX and Logging when Log4j JDK Logging Adapter is used and JaCoCo agent registers JMX MBean. Deeper investigations would require some time, in the meantime

  • either JaCoCo agent should be configured to not register JMX MBean, i.e. without jxm=true or equivalently with jxm=false (-javaagent:jacocoagent.jar=jmx=false), and should be noted that JMX is not the only option for remote connections to JaCoCo agent - have a look at output=tcpserver and output=tcpclient

  • either Log4j JDK Logging Adapter shouldn't be used, i.e. without ‑Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager

Update

And here is a ticket for a fix on JaCoCo side that explains what happens - https://github.com/jacoco/jacoco/issues/531
