Why always show,

Picked up _JAVA_OPTIONS: -Djava.net.preferIPv4Stack=true

Red colored line when I run every code in NetBeans. How can I fix this issue?

  • Thank you sir, for letting me know. I figured out that problem occurred because of user and system variables of _JAVA_OPTIONS. It resolved after I deleted that variables. – Viraj Madhushan May 27 '21 at 09:43

I have had problem (Linux OS) with

Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=on -Dswing.aatext=true

and it was solved with terminal command

unset _JAVA_OPTIONS
