your batch script isn't correct. It starts NB twice as you can see in the log. Goto is not an if/else branch.

The warnings are nothing to worry about except the last warning. I am not sure why you got this, I couldn't reproduce it with NetBeans 18 and JDK 20.

start /b bin/netbeans.exe --jdkhome "path\to\jdk"

didn't cause any issues.
