> creates the appender with a date filePattern.
> We are using a configuration like this
> {noformat}
> log4j.appender.file=org.apache.log4j.RollingFileAppender
> log4j.appender.file.layout=org.apache.log4j.PatternLayout
> log4j.appender.file.layout.ConversionPattern=%d{DEFAULT} [%t] %-5p %-33c{1} %x %m%n
> log4j.appender.file.File=foobar.log
> log4j.appender.file.MaxFileSize=200000KB
> log4j.appender.file.MaxBackupIndex=100
> {noformat}
> With log4j 1.2.17 this created rolled files
> foobar.log.1
> foobar.log.2
> etc
> With log4j2 and the bridge we get
> foobar.log2021-12-19
> We could live with the date pattern but it should produce 
> foobar.log.2021-12-19
> But since the rollover policy is still size-based what happens if the file is rolled twice a day?
