====

After some searching I tracked the problem down to a syntax error in sun-web.xml. In my particular case I was using the following construct:

<property name="alternatedocroot_1" value="from=/resources/template/* dir=/Users/neilbeveridge/temp/extroot/admin"/>

I had mistakenly inserted an opening " following the dir sub-attribute. In this case the whole from=* dir=* construct must go inside the value attribute in XML.
