英文:
Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=on
问题
每当我在Kali上通过IntelliJ执行Java代码，或者在命令行中输入 java --version，我都会收到以下消息：
Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=on -Dswing.aatext=true。
我在Google上搜索后找到了这个链接，其中描述了与我的情况完全相同的情形。但我所理解的是，这只是一条信息，而非错误，我可以取消设置 _JAVA_OPTIONS 环境变量。
我想知道的是，删除这个环境变量会不会造成任何问题？
我在上述链接中读到：“如果你删除了那个变量，信息就会消失。”
我不明白这是指会有任何损害，还是仅仅是说这个消息会消失？
最后，如何删除或取消设置这个 _JAVA_OPTIONS 变量？
更新：
当我通过以下命令取消设置这个变量：
_SILENT_JAVA_OPTIONS="$_JAVA_OPTIONS"
unset _JAVA_OPTIONS
alias java='java "$_SILENT_JAVA_OPTIONS"'
-
参考自这个链接，链接中的第二个答案 - 这条消息仍然会出现，但是会在Java程序的输出之后出现，而不是之前，就像之前那样！
英文:
Whenever I execute java code on intellij on kali, or type java --version in command line
I get this message
Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=on -Dswing.aatext=true.
I googled it and found this link that is exactly the same situation as me,
but what I understand is that it's an information not error and I can unset _JAVA_OPTIONS environmental variable.
What I'm asking for is that deleting this environmental variable will not cause any harm?
I read in the above link that If you remove that variable, information will be gone.
I didn't understand is that mean any damage or he just said that the message will gone!
And finally how to delete or unset this _JAVA_OPTIONS variable?
Update :
When I unset this variable by these commands
_SILENT_JAVA_OPTIONS="$_JAVA_OPTIONS"
unset _JAVA_OPTIONS
alias java='java "$_SILENT_JAVA_OPTIONS"'
-referenced from this link, the second answer- the message is still appear but after the output of the java program instead of before the output as it was!
