{"time":"XXX","level":"XXX","module":"XXX","class":"XXX","message":"XXXX"}

Exception in thread "main" java.lang.ExceptionInInitializerError
    ...

This does not look as the normal stack trace of a log event, but the output of Thread.UncaughtExceptionHandler. Are you sure this in the content of a log file and not on System.err?
