如何在gdb中打印Java数组？

I compiled a very simple java program with gcj-4.4 and -o option. I loaded it in gdb-7.2 and tried to do some debugging. I noticed at I could print the variables in int type but I could not print an array of int. I received this error message:

我用gcj-4.4和-o选项编译了一个非常简单的java程序。我在gdb-7.2中加载它并尝试进行一些调试。我注意到我可以在int类型中打印变量，但我无法打印int数组。我收到此错误消息：

(gdb) p orderFinish[0]
cannot find java.lang.Object
(gdb) p (int)orderFinish
$8 = -136261440
(gdb) p orderFinish[3]
cannot find java.lang.Object
(gdb) p in
$9 = 1
(gdb) whatis orderFinish 
type = int[]

So my question is how can I print a Java array in gdb? My OS is openSUSE-11.1 x64-86bit. Thanks!

Its been a while since I used GDB but p *array-variable@length should work.

自从我使用GDB以来已经有一段时间了，但是p * array-variable @ length应该可行。
