ResponseUtils.write and null properties
Is the intended behavior of ResponseUtils.write to write out the String
"null" to the print writer if the property supplied is null?
It seems that Weblogic's JspWriter will not write out "null" if null is
provided, but sun's j2ee reference server will.

Okay, actual facts for when you write that bug report against WLS:

AFAICT, the correct behavior is to output "null". This probably has nothing to
do with Struts but with the container's implementation of JspWriter.

Struts doesn't make that decision; it's up to the writer implementation.
It seems like standard Java behavior to write "null" when you try to
output a String variable that's set to null. I haven't used WebLogic but
Tomcat prints "null" and I believe a System.out.println(null) will also
print "null".
