> 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.
