Nit: this is no longer just a cert. Could you use a longer name, e.g. attestationCertChain? attestationCertOrCertAndChain? Ick.
Notes: * This is completely backward compatible to what U2F does now. * The registration request can now have more than one X.509 certificate. The chain must be DER encoded (basically, the X.509 certs are DER encoded and then concatenated one after anoter. * As noted in many comments, the leaf is in the 0th element of the chain, followed by intermediary certs. * The current code does not yet ship with the final Android attestation root CA, so all Android attestations will have "chain validated: false"

Isn't java.util.Arrays.copyOfRange sufficient? It's in jre7, at least.

This default value, combined with the for loop that will not execute for an empty caCerts list, will allow the caller to get validated = true when the caCerts list is empty. Perhaps that's what you mean, but it certainly looks odd.
