Java 8, extract JDK from .exe

• Create destination folder where you can RWX (e.g. C:\jdk8)
• Download jdk exe from Oracle (e.g. jdk-8u72-windows-x64.exe)
• use 7-Zip extract all the files from .exe
• Unzip the tools.jar found inside it into the destination folder
• In cmd.exe, run:
  • cd C:\jdk8
  • for /r %x in (*.pack) do .\bin\unpack200 -r "%x" "%~dx%~px%~nx.jar"

This solution works for JDK 8, without Admin rights.
