Jmeter启动GUI界面出错

今天要用Jmeter测试服务器性能，发现GUI界面总是有warning提示：

WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.

在网上搜了搜，发现是Jmeter需要写注册表。

解决办法如下

Problem(Abstract)

After running a clemb command under Windows 7 with Modeler 14.1 the following error is produced:

java.util.prefs.WindowsPreferences <init> 

WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs 

at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.

Cause

The error occurs because java.util.prefs.WindowsPreferences is trying to save information in HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs instead of under HKEY_CURRENT_USER\Software\JavaSoft\Prefs.

java.util.prefs.WindowsPreferences需要保存信息到HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs而不是HKEY_CURRENT_USER\Software\JavaSoft\Prefs。

Environment

Windows 7 64-bit

Resolving the problem

The work around is to login as the administrator and create the key
HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs.

以管理员身份登录，创建HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs项

虽然Jmeter不会保存任何东西到该项，仍会将信息保存到HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs。
