Confirmed on DaisyDiff 1.0 and 1.1. While the input files are themselves big, 
it could 
also be a memory leak. Notice however that the error is mentioned in Eclipse 
Code and 
not Daisy Diff. I do not have enough knowledge of the Eclipse differ to look 
into this 
(if indeed this is the problem).

Diffing is quadratic in the size of the documents. In DaisyDiff, this is the 
number
of words. The escaped document looks to have very may words, and it doesn't 
surprise
me that it's intractible to diff these documents.
Ofcourse, this doesn't prove that there isn't a memory leak.

Thanks for the insight.  In the short term, I've been trying to determine a way 
to opt 
out of running a diff all together if certain conditions are met.  It's 
figuring out 
the conditions that's the hard part.  It doesn't surprise me that this fails 
either, 
but it doesn't seem to be the size of the html at all, just the number of 
different 
elements.  "Normal" diff's between versions of the html that don't have the 
html 
escape characters works nicely, regardless of the size of the doc.
