I decompiled them and found nothing.

Of course that's not what you said, you said to GREP them. I did that and sure enough, one is referencing the new package structure, so these are not the versions of the binary frameworks I thought they were.

$ grep er.extensions.validation.ERXValidationException ERJavaMail.class
Binary file ERJavaMail.class matches

So, in the end Chuck was right. I AM an idiot. :-)
