在运行Mac OS X Snow Leopard 10.6.7的iMac上运行Java Remote Debugger JDWP时出现问题

问题描述

|| 我在工作时正在构建Spring Roo应用程序，并且远程调试器在那里工作（具有核心2 duo的27 \“ iMac），但是当我尝试在家中以调试模式（mvnDebug）运行maven时，（27 \” iMac与核心i5，也无法在我的11英寸MacBook Air 1.4GHz上运行），在显示“正在侦听地址8000上的传输dt_socket”后，程序立即冻结。 我不认为这是Maven或我的应用程序的问题，因为它可以正常工作，并且在我尝试以调试模式运行Tomcat时也会冻结，并且我尝试构建一个非常基本的Java应用程序（它只会输出一个字符串添加到控制台），它也会冻结。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

我尝试了许多不同的端口，以查看端口是否已绑定是否有问题；不是这种情况。 我尝试从Apple网站重新安装JavaForMacOSX10.6Update4，但没有解决我的问题。 这些是我的Mac上的详细信息： 型号标识符：iMac11,3处理器 名称：Intel Core i5处理器 速度：2.8 GHz 处理器：1个 核心：4个二级缓存（每个核心）：256 KB 三级缓存：8 MB内存：12 GB Mac OS X版本10.6.7 Java细节： 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VM（内部版本19.1-b02-334，混合模式） 您可以提供的任何帮助将不胜感激。我已经坚持了几天，并且正在使用\“ System.out.println \”语句进行开发以弄清楚我在代码中的位置。这太糟糕了。 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，而sudo chmod似乎也无法正常工作）：

例如，当我修复时：

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

显示一个新错误：

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有关吗？？？

解决方法

我安装了Mac OSX 10.7 \“ Lion \”及其附带的JVM，现在可以使用了。
