Each time i execute java code i get this message:
Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=on -Dswing.aatext=true
This problem has solution for windows os but i can't find any solution for linux os.
This is not warning, it is information.
It literally says that some settings were picked up from _JAVA_OPTIONS
environmental variable. It is used to configure some switches "globally" for every java application that will be run in given environment. You must have this set either on system or user level. If you remove that variable, information will be gone.
