See this blog post for more details:

Quick how-to:

• Downlad Oracle JRE installer/archive to the JRE_Installer folder. See readme in JRE_Installer and JRE_Portable folders for more details.
• Download and unpack SubGit to the Subgit folder. See readme in Subgit folder for more details.
• Double-click unpack_jre.cmd in JRE_Installer folder
• Edit subgit.cmd to set the name of the portable JRE to be used.
  • e.g.: set jre_dir=jre-8u40-windows-x64

Now you can use subgit.cmd as if you were using original subgit.bat.

Example:

c:\Path\To\SubGit-Portable>subgit --version
SubGit version 3.1.1 ('Bobique') build #3448
