我正在尝试在 Java 小程序上运行远程调试，但无法让小程序连接到调试器 (Eclipse)，也不会挂起。在启动期间，我得到以下信息：

...
    Match: digesting vmargs: -Djava.compiler=NONE -Xdebug -Xrunjdwp:transport=dt_socket,address=8088,server=y,suspend=y
    Match: digested vmargs: [JVMParameters: isSecure: false, args: -Xdebug -Xrunjdwp:transport=dt_socket,address=8088,server=y,suspend=y -Djava.compiler=NONE]
    Match: JVM args after accumulation: [JVMParameters: isSecure: false, args: -Xdebug -Xrunjdwp:transport=dt_socket,address=8088,server=y,suspend=y -Djava.compiler=NONE]
    Match: digest LaunchDesc: null
    Match: digest properties: [-Dsun.java2d.noddraw=true]
    Match: JVM args: [JVMParameters: isSecure: false, args: -Xdebug -Xrunjdwp:transport=dt_socket,address=8088,server=y,suspend=y -Djava.compiler=NONE -Dsun.java2d.noddraw=true]
    Match: endTraversal ..
    Match: JVM args final: -Xmx1g -Xdebug -Xrunjdwp:transport=dt_socket,address=8088,server=y,suspend=y -Xms512m -Djava.compiler=NONE -Dsun.java2d.noddraw=true
    Match: Running JREInfo Version    match: 1.7.0.15 == 1.7.0.15
     Match: Running JVM args match the secure subset: have:<-Xmx1g -Xdebug -Xms512m -Dsun.java2d.noddraw=true>  satisfy want:<-Xmx1g -Xdebug -Xrunjdwp:transport=dt_socket,address=8088,server=y,suspend=y -Xms512m -Djava.compiler=NONE -Dsun.java2d.noddraw=true>
...

我假设最后一行是小程序无法正确调试的原因，但我找不到有关此行含义的文档（或如何使我的 -Xrunjdwp 命令“安全”）。有谁知道在哪里可以找到这方面的文档？

负责输出的类的源代码中的注释表明这不是-Xrunjdwp问题：

// 2. Trusted command-line arguments. These come from
//    deployment.properties and are specified by the end user via the
//    Java Control Panel. It is important that such command-line
//    arguments do not affect the "secure" state of the target JVM.
//    For example, the user needs to be able to specify -Xdebug
//    -Xrunjdwp[...] via the Java Control Panel to enable debugging
//    of applets on the client machine without affecting the ability
//    of the target JVM to run unsigned applets. We consider trusted
//    command-line arguments in the satisfies() computation.

因此，尽管来源应该是一个很好的“文档”，但从快速浏览来看，我不明白为什么这不起作用。
