Right.  That is why I did not notice it first, because I am using WAS 5.1 
internally.  The problem came up with a customer on WAS 5.0.

The problem is that even if you choose an older version of J2EE, by 
default it will still use the newer compiler classes.  This would not 
cause problems with JSP, but if you write Java code, and use the 
StringBuffer class you get this silent problem.  This was a good article 
that explained it:

http://www.itjungle.com/mgo/mgo072303-story01.html

Unlike using some new JDK 1.4 class, this is a very silent problem that 
would be hard to detect.  It is the same code that you could have been 
using since java 1.2, but Java 1.4 will compile it to use new features not 
available on older versions of Java.

Great!  Now just get those repositories migrated to OS/400 :).
