java.net.BindException : Address already in use: bind - when stating tomcatx with jdk1. 8(未处于 Debug模式)

Question

在为tomcat项目搭建环境时遇到了异常

java.net.BindException: Address already in use: bind

消息很清楚:该端口已被其他进程使用。所以为了排除故障，我运行了以下命令

 netstat -aon | find "<port>"

它没有返回任何内容，因此表明该端口可供新进程免费使用。

这是我的tomcat的statup脚本，注意这里使用jdk 1.8作为JAVA_HOME

@ECHO OFF
@SET JAVA_HOME=C:\Oracle\java\jdk1.8
@SET CATALINA_HOME=C:\<project>\apache-tomcat-8.0
@SET JAVA_OPTS=-Xmx512m -XX:MaxPermSize=128m
@CALL %CATALINA_HOME%\bin\catalina.bat run

起初我以为是 tomcat8 的问题，所以我也尝试了 7 和 6。同样的问题。

之后表示怀疑jdk，所以改成1.7

@SET JAVA_HOME=C:\Oracle\java\jdk1.7

问题消失了，端口号和三个 tomcat 相同。

所以我检查了我的jdk版本

Cmd-$> %JAVA_HOME%\bin\java.exe -version
java version "1.8.0"
Java(TM) SE Runtime Environment (build 1.8.0-b132)
Java HotSpot(TM) 64-Bit Server VM (build 25.0-b70, mixed mode)

并更新(卸载+安装)到最新版本(在发布时)

Cmd-$> %JAVA_HOME%\bin\java.exe -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

所以我的问题是:

1. 我是不是哪里弄错了，还有什么我可以检查的吗？
2. 这是 oracle 的 jdk 1.8 中的错误吗？如果是，是否有解决方法？

如果还有其他需要我提供的信息，请评论。

第一次使用 jdk 1.8 运行@StephenC 引用的错误报告中的示例代码失败，并且表现与我的 1.7 实际 jdk 版本预期的一样.

Cmd-$> %JAVA_HOME%\bin\java.exe -version
java version "1.7.0_17"
Java(TM) SE Runtime Environment (build 1.7.0_17-b02)
Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)

即第一次运行正常并且服务器响应正确，第二次运行失败并出现预期的 BindExcxeption。

根据bug报告推测重现bug的1.7 jdk是

java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b05)
Java HotSpot(TM) 64-Bit Server VM (build 23.1-b03, mixed mode)

使用 Sysdeo Eclipse Tomcat Launcher plugin 从 eclipse 运行 Tomcat 7 没有出现 BindException，这是我对插件的设置

我注意到插件运行的是 javaw.exe 而不是 java.exe。我不知道这是否会有所不同。

请注意，tomxcat 在调试 模式下运行(复选框Don't run Tomcat in debug mode 未选中)。如果未在 Debug模式下运行，则会出现异常。

还可以使用 jpda 开关在 Debug模式下从脚本运行 tomcat

@CALL %CATALINA_HOME%\bin\catalina.bat jpda run

似乎可以解决这个问题。

更新

在 32 位机器(+ 32 位 jdk 和 tomcat)上的测试在 jdk 1.8 和 1.7 上都成功了。错误报告中的测试类也表现正常，即第二次运行时出现 BindException。

更新 2

该问题在计算机重启后仍然存在。这是启动过程的输出，包括堆栈跟踪，所有其他端口(10009 上的 AJP 和 10005 上的服务器本身)都已正确绑定(bind):

我认为您已被 Java 8 错误修复所困扰!

http://bugs.java.com/bugdatabase/view_bug.do?bug_id=7179799

如果您尝试绑定(bind)到已绑定(bind)的端口，Linux 和其他(非 Windows)操作系统上的 Java 总是会抛出异常。出于某种原因，这在某些 Windows 平台上的 Java 6 和 7 中是允许的。 Oracle 认为这是一个错误，并修复了它。

据推测，您正在运行 3 个 Tomcat 实例，它们都在与“穷人的”负载平衡器相同的端口上监听。您将需要找到另一种更可靠的方法来执行此操作。

更新

为了清楚起见，您不应该尝试在同一个端口上运行两个 Tomcat 实例。特别是生产服务器和测试服务器。

如果您确实设法让它“工作”，那么将不确定哪个实例会将请求发送到 IP/端口。有些可能会进入生产服务器，有些可能会进入测试服务器。简而言之，您的测试服务器将干扰您的生产服务器。

一个更好的主意是将您的测试 Tomcat 实例配置为监听与生产实例不同的端口和/或 IP 地址。
