So to contribute to this you have to sign the Oracle Contributors Agreement: http://www.oracle.com/technetwork/community/oca-486395.html

"The OCA gives Oracle and the contributor joint copyright interests in thre code."

What does 'thre' mean? ;P

They want it physically printed and signed.. sigh, I haven't printed anything in years.

Is this normal to require a scanned signature for CLAs? I noticed Apache CLA is the same (they want scanned paper signature), but all others I've seen are an online form.
