Just tell the info that is missed in the first message:
The latest "build\build-thirdparty.xml" refers to
componentref name="javassist" version="snapshot"
Then I changed it to:
componentref name="javassist" version="3.2.0.GA"
But there are other build error.
Today the "invalid CEN header" issue disappear after re-checkout CVS and build.
There is build error under tomcat directory. After removing the "tomcat" from the following two sections in jboss-head/build/build.xml, build ok.
