[log4j-announce]log4j 1.2 beta4 available

[Ceki <ce...@qo...>]

Hi all,

Log4j 1.2 beta4 has been just released. This latest version corrects a
rather annoying classloading problem.

This is what HISTORY file has to say:

  - Replaced the custom class loading based on the thread context class
     loader with a simple Class.forName() call. This solves two allied
     but distinct problems encountered when using Ant with JUnit
     although the bug is more general. In one instance of the
     problem, log4j would throw java.lang.NoClassDefFoundError for
     org/apache/log4j/AppenderSkeleton where log4j.jar and related
     classes were clearly available to the Ant classloader. In another
     incarnation, log4j would reject a custom appender claiming that it is
     not assignable to a org.apache.log4j.Appender variable. This would
     occur when log4j.jar was available to both the Ant classloader and the
     system classloader.

     Thanks to Dave Herman for providing detailed scenarios exposing
     the issues involved. See
