      Description

      I have been trying to convert our logging configuration to the groovy based configuration and have run into an issue with setting the SizeAndTimeBasedFNATP up. I used the converter tool to convert our configuration and have also tried the examples in the documentation:

      import ch.qos.logback.classic.encoder.PatternLayoutEncoder
      import ch.qos.logback.core.rolling.RollingFileAppender
      import ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP
      import ch.qos.logback.core.rolling.TimeBasedRollingPolicy

      import static ch.qos.logback.classic.Level.DEBUG

      appender("ROLLING", RollingFileAppender) {
      file = "mylog.txt"
      rollingPolicy(TimeBasedRollingPolicy) {
      fileNamePattern = "mylog-%d

      {yyyy-MM-dd}

      .%i.txt"
      timeBasedFileNamingAndTriggeringPolicy(SizeAndTimeBasedFNATP)

      { maxFileSize = "100MB" }

      }
      encoder(PatternLayoutEncoder)

      { pattern = "%msg%n" }

      }
      root(DEBUG, ["ROLLING"])

      Everything I've tried has resulted in this exception:
      java.lang.NullPointerException at ch.qos.logback.core.rolling.TimeBasedFileNamingAndTriggeringPolicyBase.start(TimeBasedFileNamingAndTriggeringPolicyBase.java:46) at
      ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP.start(SizeAndTimeBasedFNATP.java:36)
      ...

      If I step through the configuration process it appears that on line 46 in TimeBasedFileNamingAndTriggeringPolicyBase the tbrp member variable is null here.
