Derive a new class with derives from this (say SpaceRespecting...)

Make it override that method to not split on the space (but split on the other things

Change our shipped web.xml to use this and a semicolon delimiter
</li>
</ul>
<p style="margin: 10px 0 0 0">Then we submit a patch to spring which replaces that constant in the CONFIG_LOCATION_DELIMITERS with a call to a protected method which defaults to returning the same thing. This will have the same effect.</p>
<p style="margin: 10px 0 0 0">We obviously need to leave the old class in place (because of existing web.xml out in the field) and leave it splitting on space (because that is what our current web.xml uses).</p>
