MC-6399Won't login / doesnt respect JVM security provider settings (bouncy castle)
I recently installed Bouncy Castle security provider for a project I am working on. Once installed the Minecraft client stopped logging into the server I run locally. (Tho its still working for friends who connect remotely)
I get the following stack trace to the console when trying to connect with the client. The GUI eventually times out and does not connect.

If I comment out the line enabling Bouncy Castle in java.security file I still get the same error. IMO this shouldn't happen as in commenting the line Bouncy Castle is not enabled. (I've confirmed this with a simple test program showing BC wasn't available)
However once I removed bcprov-jdk15on-147 from ext it the client worked.
I see a few issues here.
For some reason the java.security provider precedence is being ignored.
Bouncy Castle is the last provider in my precedence list. Shouldn't it be using Sun, or what ever provider is working now instead of BC when it's enabled anyway?
Even when BC is not enabled in the precedence chain in java.security Minecraft is using it anyway. How and why is this so?

This ticket is invalid as it relates to a modded or 3rd party client/server.
Gee I am so glad I wasted my time in raising this issue, and it is an issue, only for it to be immediately closed.
The issue here IS with Minecraft, and not the "third party software", which for all intents and purposes is a part of the JVM.
Minecraft is not only ignoring system settings it's using a provider that isn't even enabled. Hardly a problem with the 3rd party vendor. This is Minecraft's issue.
Ok, got it. Reopened.
Minecraft includes some Bouncy Castle code. So it's probably an interaction between the code embedded in Minecraft, and the external Bouncy Castle security provider. I don't have any idea which component the bug lies in though.
Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
No answer on querry, assuming not an issue anymore.
Reopening, received the following crashlog via irc.
Having the same problem on my Mac, 10.8, using the installed Java with the system. I cannot find bouncycastle anywhere on my system (locate, spotlight, etc.).

I solved my issue. Uninstalling Java completely (using the directions at http://stikine.wordpress.com/2012/03/02/howto-remove-java/) and then reinstalling it from Apple fixed it.
Prior to that, I did try installing Oracle Java 1.7, which wouldn't launch at all.
Is this still a concern in the current Minecraft version 1.6.2 / Launcher version 1.1.2 ? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
No response in 4 months, assuming no longer an issue.
