Hi Scott,
actually we were aware of this problem when writing the checksum
computation and successfully tested it, but for some reason, which we
need to inspect further, whitespace differences nevertheless lead to
different results as you pointed out.
Yet, I think we found a fix for this issue, which will make into the 1.2
release today, so I hope that this will solve your problem.
Cheers
Edgar

I noticed that your ModelUtil.copiedEObjectToString(EObject copy,
XMIResource resource) tries to deal with whitespace serialization
differences between platforms, such as line separators and encodings.
Would passing in this EMF serialization option to Resource.save()
eliminate whitespace altogether?
getResourceSaveOptions().put(XMLResource.OPTION_FORMATTED, Boolean.FALSE);
EMF's binary format might be an option, too.
I look forward to the patch. Once the fix is in, could you let me know
what code changed so I can patch it on my side?
