Description Jan Peter Stotz 2007-01-29 00:58:44 UTC
When I add a logger entry for an inner class to my DOMConfigurator config file 
like this:

<logger name="package.MyClass$MyInnerClass"> 
  <level value="INFO"/>

I get the following warnings on the console:

log4j:WARN Continuable parsing error 59 and column 89
log4j:WARN Attribute value "package.MyClass$MyInnerClass" of type ID must be a 

I usually create by Logger classes by the command
log = Logger.getLogger(this.getClass());
and therefore the configured logger do work as expected but every time I start 
my program I get this annoying errors on the console for each logger which is 
configured for an inner class.

(Log4j 1.2.14)

This is due to the log4j.dtd file embedded in the jar file declaring that the name attribute of the logger 
element to be of type ID which prohibits the $ character.  The DOMConfigurator will log any XML 
validation errors but will otherwise ignore them which results in you getting a distrurbing warning 
message but no other negative consequence.

Fixed in rev 510723 for log4j 1.2 and 510724 on trunk.
