    Description

      When using MDC and log4j I get an IllegalAccessError during initialization.

      java.lang.IllegalAccessError: tried to access field org.apache.log4j.MDC.mdc from class org.apache.log4j.MDCFriend
        at org.apache.log4j.MDCFriend.fixForJava9(MDCFriend.java:11)
        at org.slf4j.impl.Log4jMDCAdapter.<clinit>(Log4jMDCAdapter.java:38)
        at org.slf4j.impl.StaticMDCBinder.getMDCA(StaticMDCBinder.java:59)
        at org.slf4j.MDC.bwCompatibleGetMDCAdapterFromBinder(MDC.java:99)
        at org.slf4j.MDC.<clinit>(MDC.java:108)

       I guess package private fields are not accessible between different jar-files anymore in Java 10. Or am I doing something wrong?
