Dynamic Transformation Dynamic transformation operates at some time between the JVM request for a class and the loading of that class.

Creating too many threads in one JVM can cause the system to run out of memory or thrash due to excessive memory consumption.

在一個JVM里創建太多的線程可能會導致系統由于過度消耗內存而用完內存或“切換過度”。

After this size is reached, the JVM is no longer allowed to request more memory from the operating system.

One of the simplest pieces of information shown in the Environment perspective is the location of the JVM being monitored.

在Environment透視圖中顯示的最簡單的信息之一是正在被監控的JVM的地址。

So before I write the article I set out to write (that'll come in a future column), let's take a look under the hood of the JVM.

所以，在我著手撰寫這樣一篇文章（將在未來的專欄中發表）之前，我們先來看看JVM幕后的東西。

Any other JVM using that shared class cache can subsequently execute that method as AOT code without incurring the cost of compilation.

使用這個共享類緩存的其他JVM都可以執行這些AOT代碼，這樣就避免了編譯的開銷。

Just as a JVM requires a main method, a Flex application requires a component that extends mx. core. Application as the entry point.

就像JVM需要一個main方法一樣，Flex應用程序需要一個擴展mx.core.Application的組件作為入口點。

In the next installment, I'll delve further into the functional features of a couple of dynamic languages on the JVM: Groovy and JRuby.

Also note that this API is defined to be JVM specific, so other JVMs might ignore the call or provide different behavior.

還要注意：這個API是定義為JVM專用的，因此其他JVM可能忽略該調用或提供不同的行為。
