Crash on loading after updating to technic version 4.0, critical error, binary discrepancy

I simply cannot start the 4.0 version on Technic. I opened console, and saw these lines at the end of the log (there were no exceptions or stacktraces):

[B#353] [08:49:34] [main/FATAL] [FML]: There is a binary discrepancy between the expected input class b$1 (b$1) and the actual class. Checksum on disk is 51416ed6, in patch 52fe6ed7. Things are probably about to go very wrong. Did you put something into the jar file?
[B#353] [08:49:34] [main/FATAL] [FML]: The game is going to exit, because this is a critical error, and it is very improbable that the modded game will work, please obtain clean jar files.

I should probably mention, I am using Java 8, I have tried reinstalling. There are no other errors or stacktraces, just these two lines

I'm having the same error, like exactly the same hash value mismatch. I'm on Linux, using OpenJDK-8 64bit.
I cleaned out the techinic folder and reinstalled the modpack, and got the same issue.
My friends who are on Windows are having the same issues as well.

I believe Technic is still set to use the 1.12.1 client but ATM3 has moved to 1.12.2.

What's working for me:

  1. Install as usual via Technic launcher.
  2. Click "Play" button.
    • Client crashes. This is expected.
    • This installs all the other stuff that's needed.
  3. Download 1.12.2 client jar.
  4. Replace minecraft.jar with this download.
    • You'll need to rename your download.
    • My minecraft.jar was at %USERPROFILE%\AppData\Roaming\.technic\modpacks\all-the-mods-3-official\bin\minecraft.jar. Your location may differ.
  5. Hit the "Play" button again
    • If everything went properly, it should launch as though nothing was wrong.

I can confirm that the workaround from @ouroborus work for me.
Under Linux the relevant files to swap out is here:
~/.technic/modpacks/all-the-mods-3-official/bin/minecraft.jar
I got the binary by telling technic to download the latest vanilla, and then moved the jar over.

This has been fixed. In the Technic launcher, select "Mod Options" and then "Reinstall Pack".
