The original FTB Ultimate for MC 1.4.7 crashes during startup with new versions of Java. This applies to any 1.4.7 modpack including Forestry or Railcraft. A crash might look like the following:

[SEVERE] [Railcraft] The mod Railcraft is expecting signature a0c255ac501b2749537d5824bb0f0588bf0320fa for source railcraft.jar, however there is no signature matching that description
[SEVERE] [Railcraft] Tampering Detected. Please re-download Railcraft.

Solution:

1. Download this file, name it java.security and save it in the instances base folder (the .minecraft folder)
2. Add the following Java argument to your game: -Djava.security.properties=java.security

    SpriteBatch batch;
    Texture badlogic;

    @Override

public void create () {
