初始堆大小无效：-Xms128M -Xmx512M -Xss1024K -Dlog4j.debug ...？

标签： java windows 32bit-64bit windbg

我的设置：

  • Windows 64位
  • Java应用程序加载32位本机模块
  • 可以使用32位Java（jdk1.6.0_29）和以下命令行在调试器外运行良好 - “-Xms128M -Xmx512M -Xss1024K -Dlog4j.debug ...”（为简洁而修剪）

如果我想调试本机模块，问题就会出现。因此，我使用以下powershell命令行触发64位windbg：

windbg -logo c:\dumps\dbg.log -QY -awow64exts -c "!sw;bu $entry;g;g" "$env:JAVA_HOME\bin\java.exe" $Params

$Params与用于在调试器外部运行它的完全相同的参数。

调试器启动，但会话非常短：

Finito！ Java终止在控制台窗口中打印此短消息：

Invalid initial heap size: -Xms128M -Xmx512M -Xss1024K -Dlog4j.debug -Dlog4j.configuration=file:../conf/log4j.xml -Ddozer.configuration=file
:../conf/config.properties -jar bootstrapper.jar com.shunra.bootstrapper.guice.Bootstrapper
Could not create the Java virtual machine.

任何人都可以对此有所了解吗？

修改

根据下面的一些评论，我倾向于认为我的PowerShell脚本有问题。

事实上，正如Jon Skeet建议我尝试使用相同的-XYZ参数在调试器中运行HelloWorld java应用程序并且它有效。然后是Codo的评论，这让我觉得有些东西在我的PowerShell代码中被腐烂了。

这是：

$env:JAVA_HOME='c:\Program Files (x86)\Java\jdk1.6.0_29'
$Params="-Xms128M -Xmx512M -Xss1024K -Dlog4j.debug -Dlog4j.configuration=file:../conf/log4j.xml -Ddozer.configuration=file:../conf/config.properties -jar bootstrapper.jar com.shunra.bootstrapper.guice.Bootstrapper"
windbg -logo c:\dumps\dbg.log -QY -awow64exts -c "!sw;g;g" "$env:JAVA_HOME\bin\java.exe" $Params

$Params似乎作为单个字符串传递给java进程。好的，我扩展它：

windbg -logo c:\dumps\dbg.log -QY -awow64exts -c "!sw;g;g" "$env:JAVA_HOME\bin\java.exe" -Xms128M -Xmx512M -Xss1024K -Dlog4j.debug -Dlog4j.configuration=file:../conf/log4j.xml -Ddozer.configuration=file:../conf/config.properties -jar bootstrapper.jar com.shunra.bootstrapper.guice.Bootstrapper

现在我得到了一个由java打印出来的致命错误：

Exception in thread "main" java.lang.NoClassDefFoundError: /debug
Caused by: java.lang.ClassNotFoundException: .debug
        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class: .debug.  Program will exit.

它对我的生活有什么期望？

EDIT2

根据Codo的建议改变了命令行：

windbg -logo c:\dumps\dbg.log -QY -awow64exts -c "!sw;g;g" "$env:JAVA_HOME\bin\java.exe" -Xms128M -Xmx512M -Xss1024K -Dlog4j.debug=true -Dlog4j.configuration=file:../conf/log4j.xml -Ddozer.configuration=file:../conf/config.properties -jar bootstrapper.jar com.shunra.bootstrapper.guice.Bootstrapper

现在错误是：

Exception in thread "main" java.lang.NoClassDefFoundError: /debug=true
Caused by: java.lang.ClassNotFoundException: .debug=true
        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class: .debug=true.  Program will exit.

这意味着-Dlog4j.debug=true被解释为类名，而不是JVM选项。我不明白发生了什么。
