This is what I get when trying with the latest trunk from SVN. I created a file called "errorlog" with a value of 1.
no sites file specified, setting to default: /home/davidk/swift-trunk/cog/modules/swift/dist/swift-svn/etc/sites.xml
Swift trunk swift-r5913 cog-r3459
RunID: 20120831-1448-q9y052k7
Progress: time: Fri, 31 Aug 2012 14:48:28 -0500
Iteration :: 0
the value is: 1
Iteration Read :: 0
Execution failed:
java.lang.NullPointerException
