New subject: SLF4J+logback not working with JDK9 (Jigsaw) early access

19 Oct 2015

      Hi,

Just an FYI.

I've been doing early-access testing of JDK9b83 (project Jigsaw modular
build from https://jdk9.java.net/jigsaw/)

The first call to LoggerFactory.getLogger(Class clazz) fails with the
exception:

Failed to instantiate [ch.qos.logback.classic.LoggerContext]
Reported exception:

The program continues but there is no log output.

This is with

slf4j-api-1.7.7.jar
logback-classic-1.1.2.jar
logback-core-1.1.2.jar

If I remove the logback jars and replace with slf4j-jdk14-1.7.12.jar then
it works fine.

Cheers,

Chris
