java - 在运行 Mac OS X Snow Leopard 10.6.7 的 iMac 上运行 Java 远程调试器 JDWP 时出现问题

Question

我正在工作中构建 Spring Roo 应用程序，并且远程调试器可以在那里工作(带有 core 2 duo 的 27"iMac)，但是当我尝试在家里以 Debug模式 (mvnDebug) 运行 Maven 时(带有 core i5 的 27"iMac，也无法在我的 11"MacBook Air 1.4GHz 上运行)，程序在显示“正在监听地址:8000 处的传输 dt_socket”后立即卡住。

我不认为这是 Maven 或我的应用程序的问题，因为它在工作中工作正常，并且当我尝试在 Debug模式下运行 Tomcat 时它也会卡住，而且我尝试构建一个非常基本的 Java 应用程序(它只是向控制台输出一个字符串)，它也卡住了。我相信这与 Mac OS X 或 Java 有关。

这些是我用来运行调试器的参数:

-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000

我尝试了很多不同的端口，看看是否是端口已经绑定(bind)的问题；事实并非如此。

我尝试从 Apple 网站重新安装 JavaForMacOSX10.6Update4，但它没有解决我的问题。

这些是我的 Mac 上的详细信息:

• 型号标识符:iMac11,3 处理器
• 名称:英特尔酷睿 i5 处理器
• 速度:2.8 GHz 数量
• 处理器:总数 1
• 核心:4 个二级缓存(每个核心):256 KB
• L3 缓存:8 MB 内存:12 GB
• Mac OS X 版本 10.6.7

Java 详细信息:

• java 版本“1.6.0_24”Java(TM) SE
• 运行时环境(内部版本 1.6.0_24-b07-334-10M3326)
• Java HotSpot(TM) 64 位服务器虚拟机(版本 19.1-b02-334，混合模式)

如果您能提供任何帮助，我们将不胜感激。我已经在这个问题上坚持了几天了，并且一直在使用“System.out.println”语句进行开发，以找出我在代码中的位置；太可怕了。

编辑:

我似乎遇到了无法修复的权限问题(磁盘实用程序无法修复它们，并且 sudo chmod 似乎也不起作用):

例如，当我修复时:

User differs on "System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Libraries", should be 95, user is 0.

出现新错误:

User differs on "System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Libraries", should be 0, user is 95.

也许这与 Java 6 Update 4 有关？？？

我安装了 Mac OSX 10.7“Lion”及其附带的 JVM，现在可以运行了。
