    Description

      Have pushed a repo with single test case demonstrating the issue:

      https://bitbucket.org/tomhaines/logback-npe-148-mdc/src/master/

       
      Starting in 1.4.8, the following NPE occurs:

      Cannot invoke "ch.qos.logback.classic.LoggerContext.getMDCAdapter()" because "this.loggerContext" is null
java.lang.NullPointerException: Cannot invoke "ch.qos.logback.classic.LoggerContext.getMDCAdapter()" because "this.loggerContext" is null
at ch.qos.logback.classic.spi.LoggingEvent.getMDCPropertyMap(LoggingEvent.java:407)
at com.logback.example.StackJsonLayout.createContextNode(StackJsonLayout.java:74)
at com.logback.example.StackJsonLayout.doLayout(StackJsonLayout.java:60)
at com.logback.example.StackJsonLayoutTest.testBasic(StackJsonLayoutTest.java:22)

      To replicate, run

      ./gradlew test

      If you change back to logback 1.4.7 via gradle dependencies, the test passes.
