Nutch and OSCache

I'm wondering if anyone is running OSCache with Nutch?
 
Ive followed there tutorial, and it seems there is a issue when wrapping any custom tag around any flushed include, which is according to JSP specification. I guess there is one in the Nutch JSP code stopping me?
 
Looking at the log output, Nutch runs fine and the point of error is the page generation.

I know this isn't really a Nutch issue per say, but if anyone is running it without problems any tips would be greatly appreciated.
 
Thanks,
