Heisenbug. ClassCastException SubstituteLoggerFactory

[d10xa]

Sometimes following code fails:

LoggerFactory.getILoggerFactory
.asInstanceOf[LoggerContext]
.getLogger("ru.d10xa.jadd")
.setLevel(Level.DEBUG)

with:

java.lang.ClassCastException: org.slf4j.helpers.SubstituteLoggerFactory 
cannot be cast to ch.qos.logback.classic.LoggerContext
 at ru.d10xa.jadd.LoggingUtil$.rootLogger(LoggingUtil.scala:17)
 at ru.d10xa.jadd.LoggingUtil$.quiet(LoggingUtil.scala:25)

Temporary fix with pattern matching

LoggerFactory.getILoggerFactory match {
  case l: LoggerContext =>
    l.getLogger("ru.d10xa.jadd").setLevel(Level.DEBUG)
  case l: SubstituteLoggerFactory =>
    def logger = l.getLogger("ru.d10xa.jadd")
    println(s"SubstituteLoggerFactory used. Can not enable debug mode ${logger.getClass}")
}
