Hi
As state in the javadoc it should throw NullPointerException if name
is null (wich make sense). But in the code they also throw an exception
if the the value (o) is null!

java.lang.Object o,

I am guesing it was a fix for spec compliance:

Hi all,
I just installed a fresh tomcat 4.1.31 and run into this problem.
From 4.1.30 to 4.1.31 the PageContexImpl.setAttribute has change in a
way that make it unusable. I cannot set null attribute in the
pageContext ?!?!?!
So the following call throw an exception in 4.1.31:
pageContext.setAttribute(LOOKUP_GROUP_DATA_KEY +
enclosingGroup.getGroup(), null, PageContext.REQUEST_SCOPE);
Is that mean I need to check if an attribute is null before putting
it into the pageContext.... It desn`t make sense to me?
This change make 4.1.31 totally unusable for me... Any idea on what I
can do? Or where I'm wrong?
Thanks for your help!
