Xalan & Docbook: adjustColumnWidths Error

I'm trying to build some HTML documentation by running xalan from a scons script. However, it's crashing due to an adjustColumnWidths error. I've put in the extensions .jar and param statements other users said solved the problem, but it still isn't working. Could you please look over the function call & error and see if I'm forgetting something?

Here's the call & error:
