The tampered.jar is a jar file that originally was correctly signed, but then was "tampered with"
by truncating the Main.class file. It was built with these commands:

keytool -genkeypair -v \
  -keystore codesignkeystore.jks \
  -keyalg RSA \
  -keysize 2048 \
  -alias codesignkey \
  -dname "C=US, O=ExampleOrg, ST=Washington, L=Seattle, OU=None, CN=www.example.com" \
  -storepass password1234 \
  -keypass password1234 \
  -validity 18250

echo 'public class Main { public static void main(String[] args) { System.out.println("Hello, World!"); } }' > Main.java
javac Main.java
jar cfe tampered.jar Main Main.class
jarsigner -keystore codesignkeystore.jks -storepass password1234 -keypass password1234 tampered.jar codesignkey

unzip tampered.jar -d tmp_jar_directory
rm tampered.jar
rm tmp_jar_directory/Main.class
touch tmp_jar_directory/Main.class

(cd tmp_jar_directory && zip -r ../tampered.jar .)
