Well actually I've had to find on my own that this is caused by using JDK. Since most answers for posts on this topic was to restart pc And if someone used tekkit on computer with JDK, without any knowledge of java I highly doubt that he would ever think about resolving "Authentication error" issue by looking what kind of java he has installed. No, but confusing error messages can. This is not minecraft issue, minecraft works fine with JDK. Its issue with tekkit launcher that can't work with JDK. And instead of saying so, it tells me that there is authentication error. In what way, is using JDK an authentication error? By the way even if it was minecraft issue (which is not) it would still be nice if launcher informed you... I did, but thats not the issue (even if its the cause of auth error). Issue is confusing error message caused by using JDK.

Minecraft worked ok for me even with JDK. But still tekkit launcher should write some error message that would explain what is wrong.

Because I run minecraft on pc that did not have JRE, since I use it for java development. I do not care if I can not use JDK, but if tekkit launcher does not work with JDK, you should not be able to launch the launcher with it. And not just see completely irrelevant message like "Unable to authenticate account with minecraft.net" "We don't help pirate accounts." Wtf? How can you even assume something like that from this bug report? I submit a bug report and someone just starts accusing me of piracy because of it? And I highly doubt that there is something in place that could prevent such things...

Launcher Version: 1.1.2.0 Operating System: Windows 7 x64 Java Version: JDK 1.6 Antivirus Program: Description of Problem: When you try to run tekkit with JDK (instead of JRE) launcher will be unable to authenticate account (with no additional errors in log). And such error is very confusing. Error Messages: Unable to authenticate account with minecraft.net Error Log:
