Please specify:

• JRI version
• Tomcat version
• OS version
• Java version used by Tomcat (you can see it on the JRI homepage, either http://server:port/jri or http://server:port/JasperReportsIntegration, depending on your JRI version

Thank you

Thank you for raising this. There seems to be an issue with log4j and Java 11. I will need some more time to fix this: https://stackoverflow.com/questions/53049346/is-log4j2-compatible-with-java-11

In the meantime, please use a Java environment below Java 11 like Java 8, 9 or 10. Java 8 will definitely work (I develop/test on this), the others might as well.

LogManager.getLogger() doesn't work any more in JDK11. Specifying the class explicitly is mandatory.
