Bouncy Castle has supported them at least since early ESAPI 2.0RC days.
Oracle started supporting them in SunJCE in JDK 7. So, I guess the answer
is YMMV. IMO, it's still too early to make them the ESAPI defaults, but
IMO, if you can use them, you should. Based on feedback from professional
cryptographers, I'd probably recommend CCM over GCM as the latter is a bit
"twitchy" and much harder to eliminate timing side channels. Consult with
the crypto policies of your company and/or local company crypto guru before
making any changes though.
