I tried to build Nutch on Windows XP Pro and Debian Linux Woody, both with
ant 1.6.2 and Java 1.4.2, it worked well but i still get this error-message
when i try to compile it on Sarge.
Java Version: 1.4.2_08
I get this when I type "java -version": Just-in-time v3 Version: 1.1.x.cvs
Java Version:1.1
Ant Version: 1.6.2 compiled on July 16 2004
Nutch Version: Reversion 165124 downloaded today.
System: Debian Linux Sarge, downloaded on 20 April 2005
