attempting to decompile the launcher

[justa]

as the title says, I'm attempting to decompile the minecraft launcher, but I'm having problems..

what the problem is:

when I open the launcher and write username/password in the textboxes and press login, it will say in red above the text boxes and buttons in the login form "java.lang.NullPointerException" and in the console:

E:\Files\Minecraft\Client\Launcher\src>java net.minecraft.LauncherFrame

if someone could help me, tell me what the problem is, that would be great.

I attached the java files in the rar archive...

Elitepvpers does not support illegal Things and dekompilen of Things is illegal

[justa]

mojang does however allow modding of their files... so to mod we have to decompile

otherwise i would like an admin to lock this topic

[False]

Even the launcher?
Where can I find the decompiler?

[justa]

the MCP is developed by users, not Mojang, or any of its employees..

so if decompiling the launcher is illegal, then decompiling the client/server is too.

read "Special thanks to"

btw I made my "own" launcher with c++ now and no more require help.
