I was just about to quote this myself.
Perhaps this is not a Tomcat issue per se, but rather a gray area of the
Servlet spec.
Obviously a NullPointerException is being thrown at some level, but Tomcat
is catching it and apparently just replacing it with "", this is acceptable
in that Tomcat is following the letter of spec, so to speak, but definitely
not following the "spirit" of the java in general, imho.
