Support multiple java paths via config or `JAVA_HOME`

I'm running a 1.17 and a 1.12 minecraft server which require two different versions of Java 8 and 16
I have java 16 as my env variable I was wondering if I can do something like change line 71

private Process GetJavaProcess(string args)
{
var javaPath = JavaHelper.FindJavaExecutableAbsolutePath(); <<<<
return new Process
{

to

var javaPath = "C:\Program Files\Java\jre1.8.0_291\bin\java.exe";

However when I make that change with or without "" it unloads the plugin and shows an error on reload. I hope it's relatively easy thanks.

Start at the GetJavaProcess method around line 71 and inspect JavaHelper.FindJavaExecutableAbsolutePath(). Reproduce the reload error with the hard-coded path, then trace how the plugin starts each server. Done means separate Java paths can be selected through configuration or JAVA_HOME without unloading the plugin or failing on reload.
