Error Deserializing EOGlobalID via Web Services

Hi,

I'm trying to return a EOGlobalID (specifically, EOTemporaryGlobalID) from a method provided via WebObjects's Web Services. However, I'm getting an "IllegalArgumentException" and I'm not sure why this is so. I've reduced the problem to a very simple scenario. WOApp 1 calls a no-argument web service method on WOApp 2, which returns a EOGlobalID. Anyone have any ideas on what's causing the exception? Here's the stack trace:
