after removing lib/jetty-ext/ant.jar, these warnings disappear (and
the BUILD is successful).

I am using ant version 1.7.0, sun jdk1.6.0_01, and head of Hadoop
source tree (as of 6/14).

As for OS,
   Linux 2.6.18-8.1.1.el5 #1, SMP, x86_64

which version of ant are you guys using?  also which version of
ant.jar is jetty-ext/ant.jar.
I can try to downgrade to the "ant" version that is the same.
