Damn, you'd think with 200k lines of awesome Java that needs to be documented with a manual that's hundreds of pages long that uses 3 other massive Java projects and released by a government agency that's done backdoors in everything from crypto systems, operating systems, to even backdoors themselves, that there'd be at least a plausibility of them putting one in.
That's just from a quick google. Back in the day there were stories of "A Visit from Mr. Brown" or something like that. The NSA or "some agency" would go around to anyone making crypto or operating systems and ask to be given backdoors in exchange for deals on export restrictions. Periodically a government agency in another country would find them and we'd be embarrassed. These days it's not as common since crypto exports aren't restricted (much) so the threat of, "If you don't add a backdoor we'll label your software a weapon and you can't sell it to the world." doesn't work.
Then again, could all just be a huge conspiracy.....mwhahahaah.
Oh, the great Bruce Schneier says so, so therefore it must be. How do you know he's not a shill for Microsoft and the NSA? Hmm?
The great thing about backdoors is, when they get discovered they have perfect plausible deniability. "Oh that key named NSAKEY isn't for the NSA it's for...uh...this other agency. Yeah that's it! It's not even a key. Right Bruce? Right?!"
They are an eco-friendly CO_2 emission reducing measure to reduce workload, in a desperate attempt to comply with KIOTO. They needed it to conform to the Energy Star certification scheme from the DoE.
