Enabling JVM options with Java Web Start / JNLP
提问by mikera
I'm creating a Web Start application which would benefit from some of the newer JVM options (especially escape analysis, G1 garbage collector etc.)
我正在创建一个 Web Start 应用程序，它将受益于一些较新的 JVM 选项（尤其是逃逸分析、G1 垃圾收集器等）
At the same time, I would like the application to work gracefully on older JVMs that do not support these options.
同时，我希望应用程序能够在不支持这些选项的旧 JVM 上正常运行。
Is there a good way of achieving this?
有没有好的方法来实现这一目标？

As Thorbj?rnmentioned, Java 6 u10 allows multiple j2seelements in JNLP. The JNLP File Syntaxresourcessection of the latest Java Web Start Developer's Guide, indicates that multiple j2seelements, each with java-vm-argsattributes can be specified with the most preferred occurring first. For example:
正如Thorbj?rn 所提到的，Java 6 u10 允许j2se在 JNLP 中使用多个元素。最新的Java Web Start Developer's Guide的JNLP 文件语法resources部分指出可以指定多个元素，每个元素都具有属性，最喜欢的首先出现。例如：j2sejava-vm-args
<j2se version="1.3" initial-heap-size="64m" max-heap-size="128m"/>
<j2se version="1.4.2+" href="http://java.sun.com/products/autodl/j2se"
java-vm-args="-esa -Xnoclassgc"/>
