Just a guess, but there's a version of getBytes that takes a character set name as an argument, which would probably throw a NullPointerException in the event that the argument you passsed it was a null string. Take a look at http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html#getBytes(java.lang.String) and see if there's a chance that your HttpServletWrapper line 346 could be passing null for the character set name.
