In java program, When I try to compile some code it creates an error I get this message:
Picked up _JAVA_OPTIONS: -Xmx512M
what type of error is this the page Suppressing the "Picked up _JAVA_OPTIONS" message
cannot solve problem ,how to change system variable in windows 7 ??
It is output by the java command when it sees that the JAVA_TOOL_OPTIONS or _JAVA_OPTIONS environment variable is set and when the user is not privileged. The behavior is hardwired, and the java command doesn't provide a way to suppress it.
You can use _JAVA_OPTIONS to pass options to any JVM process started on your system. For example, set _JAVA_OPTIONS=-Dsun.java2d.noddraw=true. When a JVM starts, it parses the value of _JAVA_OPTIONS as if the parameters were at the command line of java. You can see the passed parameters via JVisualVM.
From the Start Buttong, search for System, then launch "System" from your search results. In the new window, select Advanced System Settings. A new window will open, select the Advanced tab, then click on the Environment button. In this new window, select _Java_Options, in the user variables and then click on Delete.
conf. /etc/environment.
Go to my computer and right click on top of that and click on properties, a new window will open like below.
then click on advanced system setting
then click on environment variable and delete _JAVA_OPTIONS from user variable and then try again.
Part of my original answer was truncated, so here is the edited answer:
From the Start Buttong, search for System, then launch "System" from your search results. In the new window, select Advanced System Settings. A new window will open, select the Advanced tab, then click on the Environment button. In this new window, select _Java_Options, in the user variables and then click on Delete. If the lower section, System Variables, is greyed out and you cannot delete _Java_Options there, you will need to log on as an administrator, or attempt to run the "System" command as Administrator.
You have to delete your environment variable named "_JAVA_OPTIONS" going to system, advance settings. Save, close your project and restart.
