linux - Eclipse Kepler 经常因 java.net.UnknownHostException 崩溃

Question

我在 Opensuse 13.1 上的 Eclipse Kepler 经常崩溃(每天大约 5 次)。在错误日志中我看到了这个:

java.net.UnknownHostException: chmalap.site: chmalap.site: Name or service not known at java.net.InetAddress.getLocalHost(InetAddress.java:1473)

chmalap 是我的电脑在本地网络上的主机名...但他为什么要查找这个？我的 Eclipse 是最新的(8.2.1，我没有配置太多设置。我安装了 EGit 和 SVN 插件。有什么想法吗？

这里是完整的崩溃信息

编辑:根据 Greg-449 的建议，我停用了 RSE UI...但是我的 eclipse 再次崩溃了。这次只有这些错误出现在错误日志中(它们之前已经出现在错误日志中；但总是在崩溃之前；在我看来，它们在崩溃的那一刻不存在)

为了安全起见，我删除了这些快捷方式中的每一个，因为我不使用它们......但它们对我来说似乎不是严重错误

Answer 1

这似乎是 Eclipse RSE(远程系统资源管理器)正在执行一些初始化，但遇到 InetAddress.getLocalHost 问题。

如果您不使用 RSE，您应该能够通过转到 Preferences > General > Startup and Shutdown 来停止此初始化。取消选中 RSE UI 复选框，这应该会阻止 RSE 初始化在 Eclipse 启动期间运行。

更新: 看起来这可能是 Eclipse bug 323606 .错误报告说它是由以下原因引起的:

Initialize system using DHCP and don't register ip address/hostname with DNS
