Question

我正在Eclipse中从事Java项目。我可以启动应用程序（运行方式），我工作正常，但我无法启动调试为（我可以启动调试为但突然我不能再）。有没有人有这种奇怪的东西？

Answer 1

我已经看到这两个菜单分别对他们的目标感到困惑。例如，对于Ant构建文件，将继续标题为“Run As＆gt; Ant Build”，另一个将标题为其他内容，并失败。

重启Eclipse始终解决了这个问题。

Answer 2

基于（格式不正确的）答案确实应该是问题的一部分，看起来你的套接字地址可能不正确。

对于INetAddress.getLocalhost ...反复重复NumberFormatException ...

啊！你有IPv4或IPv6吗？如果v4（十进制）解释器试图解析v6（十六进制）地址，事情可能会被破坏。

也可能是你的调试套接字号不是一个数字（至少不是十进制数）...但是我没有看到UI中的任何地方来调整这个，所以我看不出你怎么做打破了它。

Answer 3

仅仅是因为将来有人会遇到同样的问题。最近我被相同的用例（但在NetBeans中）所欺骗 - 问题是由java.lang.IllegalArgumentException上的断点造成的，我前段时间创建并忘记了它，所以IDE一直停在某处Java核心代码只是因为该断点，但我认为它是由我的代码或运行时环境中的某些东西引起的：（

实际上，我会说这个问题在核心Java库中是一般的编码风格。在if（）条件更合适并且在调试异常时导致主要问题的情况下，有很多地方会抛出异常 - 它们中有太多。在那个特例的情况下，它是由以下几行引起的（我从这里http://download.java.net/openjdk/jdk6/获取了InetAddressCachePolicy的来源）：

    try {
        tmp = new Integer(
          java.security.AccessController.doPrivileged (
            new PrivilegedAction<String>() {
              public String run() {
                  return Security.getProperty(cachePolicyProp);
              }
          }));
    } catch (NumberFormatException e) {
        // ignore
    }

你可能会注意到编写代码的人知道配置中提供的潜在'not-a-number'字符串，但是没有尝试更优雅地处理，至少String的情况是null或为空，这实际上是这个问题的案例。
