Sounds like exec isn't parsing the string the way a shell would, and
kadmin.local sees a separate "-pw" argument and takes that as an
indication that the principal name is "w". According to http://
java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html#exec
(java.lang.String) the string is parsed using a StringTokenizer that
doesn't understand quoted strings in the input.
Probably you want to use the exec(String[]) method instead, and
construct the argument array yourself, either as an array directly,
or by more shell-like tokenization.
