When will the 64-bit version of JDIC be available?

Question

我的Java程序需要大量内存才能运行，32位版本的Java最大内存为1.5 GB，我的系统具有4 GB RAM，因此我决定在64位版本的Java下运行它，但是JDIC将不起作用，这会影响我的程序，所以我想知道是否有人知道何时可以使用64位JDIC？

Answer 1

Assuming you are running a 64-bit OS and a 64-bit JVM, you could try the latest version of Java 6u13 as I believe there is improve client side support for 64-bit applications.

Note: I wouldn't suggest you use more than 1/2 to 2/3 of your memory for Java's heap. You may also need more main memory to see a real improvement in the amount of memory you can really use. (As you need to leave memory for the OS, other programs and Java's own shared memory/libraries etc)

Answer 2

我只使用了JDIC的Desktop（org.jdesktop.jdic.desktop.Desktop），现在可以使用Java 6的java.awt.Desktop。虽然有一些区别，但是本质上它们具有相同的功能。
