Cannot recognize installed JDK on Windows 10 using Zulu OpenJDK 11

### Problem Description

Running `boot.exe` results in:

> This application requires a Java Runtime Environment 1.7.0
> The registry refers to a nonexistent Java Runtime Environment installation or the runtime is corrupted.

Leiningen (via `lein.bat`) works as expected on the exact same setup.
I was able to get boot working in bash (from the Git BASH distribution) using `boot.sh`, but boot.exe results in the message above using both cmd.exe and PowerShell.

### Steps to reproduce

1. Download boot.exe - https://github.com/boot-clj/boot-bin/releases/download/latest/boot.exe
2. Put it in a path included in the `PATH` env variable
3. Launch cmd.exe or PowerShell
4. Run `boot.exe`
5. The message reported above appears and a browser window opens Oracle's JDK dowload page.
