May you please post your stack trace?

I also need something I can reproduce the NPE. Do you have an example file?

> When parsing appender filters configured in the properties file for example:
> {code:java}
> log4j.appender.LOG_REQUEST_START_DB=my.appender.class
> log4j.appender.LOG_REQUEST_START_DB.filter.ID=my.filter.class{code}
> a NullPointerException is thrown on line 564 of org.apache.log4j.config.PropertiesConfiguration. The _next_ variable is always _null_ at that point, from what appears to be a bug in the _if_ condition above (looks like it should be _head == null_ instead of {_}head != null{_}).

> Note: this is using the log4j1.compatibility=true property
