Okay, I’ll add a comment. > Too bad IceTea’s build system doesn’t take care of that. Yeah, there is an old bug report about this, but its resolution has been pushed to later releases repeatedly.

It actually depends on the arbitrary value of “recent”, which I set to 2016-1-1, but I must admit that I don’t know if we really must filter out invalid certs at all. I don’t know if it is a problem if invalid certs are part of the keystore. Maybe it’s not an issue. ~~ Ricardo
