NoSuchMethodException when running a search

[GoogleCodeExporter]

What steps will reproduce the problem?
1. build an index with the wiki-small dataset 
(http://www.search-engines-book.com/collections/).  This completes normally.
2. run 'galago search <wiki-small index>'
3. go to the URL specified and run a query

What is the expected output? What do you see instead?
Instead of search results, the returned page is empty with the following 
exception printed to std. out:
