Re[2]: LinkageError while running junit task

[Jacob Kjome <ho...@visi.com>]

Hello Dominique,

I have also noticed that JUnit needs to be loaded into the classpath
at the same time as the optional.jar...meaning that if optional.jar is
in $ANT_HOME/lib, that is where the JUnit.jar needs to be.  Also, it
seems that JUnit-3.8 only works with Ant-1.5+ and not Ant-1.4.1.

Hope that helps,

jake
