My launcher keeps crashing and I don't know why. It starting happening right after I updated to the new version that came out today. I can show you what the console says, but other than that, I don't know what happened.

Ive seen no replys from any one on how to fix it... funny thing is that none of the mods comment on it

This is still fairly new, if anything they're either A: trying to replicate it, B: sleeping/chilling with family or stuff (it is sunday in europe) C: re-syncing the launcher to the DL servers or D: already realize what the problem is and are trying to fix it. give it time. besides, it isn't too big of a deal yet.

The problem seems to be the logic that tries to find all Java installs (JavaInfo.java). It makes the assumption that every version of java has 4 parts - major, minor, revision, and build. However, this is not the case. Some installs of Java don't have a build number. For example, these are the installs present on my system (in c:\program files\java):
jdk1.6.0_24
jdk1.6.0_30
jdk1.6.0_33
jdk1.7.0
jdk1.7.0_25

Note that jdk1.7.0 has no build number. So the code attempts to split into 4 parts and read all 4 parts... hence the ArrayIndexOutOfBoundsException with value 3, because this version doesn't have a 4th part (index 3).

The solution for me was to uninstall jdk1.7.0, since it's an older version of Java and I don't need it.

Confirmed removing 1.7.0 worked! I spent many hours before reading this trying to get it to work, gave up and had a friend zip me his files. Thanks a lot!

Assuming you're using windows, you can uninstall it from the control panel. The fix seems to have been implemented in the next launcher version, so as soon as that is released, the problem should be solved in any case.
