This is the line in question: "Picked up _JAVA_OPTIONS: -Xmx512M" It seems that you have set an environment variable named "_JAVA_OPTS" which is interfering here. You'll have to remove it in order to fix this. What kind of operating system do you have?
Some other program may have set that as an environment variable on your system. First reboot if you didnt try that already. Next open a command prompt. (Right click start button -> Command prompt). Type "SET" by itself. This will list all your environment variables. See if _JAVA_OPTIONS is listed, since it starts with an underscore, it will probably be alphabetically sorted at the very top or bottom. If it is NOT listed, then your launcher must be setting it somehow. Not sure where to go from there except maybe a reinstall. If it IS listed, follow the instructions on how to set a system environment variable on this page. How do I set system environment variables in Windows 10? - Super User The third post down the page will probably be the most helpful to you. You need to delete the _JAVA_OPTIONS variable.
