Hi Ralph,

Please let other lists know about your conclusions as appropriate. I am not

[snip]

The internal log4j messages are sufficient to diagnose the problem. For 
some reason, the root logger is parsed twice. When PropertyConfigurator 
parses a file, each time it encounters a logger, it starts by closing all 
the appenders attached to that logger. Since the root logger is configured 
twice, the stdout appender is attached to root the first time the root 
logger is configured. In the second round, all the appenders in root are 
closed. Thus, stdout is closed. However, it since it is mentioned in root 
logger, it is attached to root logger again but it is already closed.

Either the log4j.properties file that ships with jakarta-poi-1.5.1-final is 
buggy or there is a problem with the
java.util.Properties implementation in your environment.
