使用 Xmx 增加 JVM 堆 memory 不起作用

Question

I'm developping a javafx application which has much ui interfaces, and while opening many windows, the jvm start consumming much memory ( going up tp 350mb ). I'm developping a javafx application which has much ui interfaces, and while opening many windows, the jvm start consumming much memory ( going up tp 350mb ).

When it arrives to 360mb , the programs starts lagging and end up by being crashed (nothing works, screen blocks...) and the console show a OutOfMemoryException with Java Heap Space error当它到达360mb时，程序开始滞后并最终崩溃（没有任何效果，屏幕阻塞......）并且控制台显示OutOfMemoryException和Java Heap Space error

I've 6gb of memory in my computer, and tried to start the .jar file using -Xmx param, but still the operating system doesn't allow the jvm to consume more memory.

Is there anything else i should specify so that the jvm may be able to get as much memory as it needs?还有什么我应该指定的，以便 jvm 可以获得尽可能多的 memory 吗？

Answer 1

You might want to ensure that you're using:您可能希望确保您使用的是：

java -Xmx1024m -jar YourApplication.jar

and not:并不是：

java -jar YourApplication.jar -Xmx1024m

Anything after the.jar is considered as argument passed to your executable Jar. .jar 之后的任何内容都被视为传递给可执行文件 Jar 的参数。
