hi all,

I have come into a very wired problem.

here it is.
my project using JBuilder 2006 and tomcat 5.5.20.
when i put a 0 into a list and get 1 as a result.
simple code for testing!

List alist =new ArrayList();
alist.add(0);  put 0 into it
alist.get(0);   get 1 as result.

it occurs when i using JBuilder2006 to complie it and run under tomcat
5.5.20.
i choose Jbuilder 2006 builder property: language features ( java 2 SDK
V5.0 generic enable) ; target VM  java 2 SDK V5.0 and later

 but if i choose target VM   target VM  java 2 SDK V1.4 and later   it
works fine, put 0 get 0.
and if i donot run under the tomcat it still fine

so i create another small  project, in a jsp only doing  List alist =new
ArrayList();
alist.add(0);  alist.get(0);
and it works fine as well under the same tomcat.


i wonder what happens here?
 my project using many other jar file , i wonder if there is  something
wrong there.
does anyone has a idea?

thanks in advanced!
