1.Eclipse CDT是开发C/C++的
2.现象：
直接使用Eclipse IDE for C/C++ Developers可正常编写运行、调试c/c++
使用Eclipse for RCP RAP，已集成了MyEclipse，再安装Eclipse CDT插件时，只能正常运行，但是无法调试程序，运行调试时报异常（貌似是spring ide插件工具和CDT有冲突，毕竟是java开发环境来开发c/c++）：
Java代码

解决：
创建插件项目，引入CDT依赖包，org.eclipse.cdt.dsf.gdb.launching.LaunchUtils.getLaunchEnvironment(LaunchUtils.java:389)处设置断点，观察问题现象
通过2种不同的目标插件平台：a) 集成了MyEclipse的eclipse RCP 和 b) Eclipse IDE for C/C++ Developers，对比发现他们获取到的env内容有差别，关键在bundle_loc、bundle_state_loc、bundle_version这三个，这三个在org.springframework.ide.eclipse.core/META-INF/MANIFEST.MF中参考代码
因为对CDT和Spring IDE插件都不了解，治标修复LaunchUtils代码，getLaunchEnvironmen方法中的envMap.put(var.getName(), var.getStringValue());替换为：
Java代码
try {
envMap.put(var.getName(), var.getStringValue());
} catch (IllegalArgumentException e) {
if (var.getName() == null || !var.getName().startsWith("bundle_")) throw e;
ResourcesPlugin.getPlugin().getLog().log(new Status(IStatus.INFO, GdbPlugin.PLUGIN_ID, "ignore env variable [" + var.getName() + "] fetch error!", e));
}

替换包org.eclipse.cdt.dsf.gdb_3.0.0.201102110609.jar中的二进制代码即可

zip包是LaunchUtils.class代码
