[BUG] Betacraft Portable Jar crashes with portable JRE

[ItsFoxy87]

Describe the bug
When installing a portable JRE (version 8) and the portable JAR of the Betacraft launcher to a USB, trying to run the jar with java.exe or javaw.exe shows a console window for a moment before silently crashing with no errors or logs.

To Reproduce
Steps to reproduce the behavior:

1. Set up USB with JAR portable launcher and portable JRE (I have tried both JDKPortable and jPortable from PortableApps)
2. Set up a batch file as shown below to run the application with the installed JRE
3. Run batch file
4. Command prompt window opens and immediately closes, no running processes, errors or logs.

Batch file:
@echo off "%~d0\JDK64\bin\java.exe" -jar "%~dp0launcher-1.09_17-portable.jar"

Expected behavior:
Launcher should run and function as intended.

Desktop:

• OS version: Windows 11
• Launcher version: 1.09_17
• Desktop environment: Default Windows
• Processor architecture: x64

if your launching from batch make sure the entire path has no "(" or ")" and avoid special characters this is not a betacraft or java issue but batch itself. Secondly echo off should be it's own line.

Unable to reproduce most likely an issue with your batch

@ECHO OFF
"%~dp0jdk8u472-b08/bin/java" -jar "%~dp0launcher-1.09_17-portable.jar"
pause
