JRebel Windows RegCreateKeyEx(...) returned error code 5.

做为一个JRebel的深度用户,在win10下用JRebel的eclipse插件使用的时候遇到了以下问题:
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.

这是一个warning,虽然不影响使用,但做为一个有洁癖的人怎么能容忍!java

解决方案以下:node

  1. Go into your Start Menu and type regedit into the search field.
  2. Navigate to path HKEY_LOCAL_MACHINE\Software\JavaSoft
  3. Right click on the JavaSoft folder and click on New -> Key
  4. Name the new Key Prefs and everything should work.

偷懒的同窗能够直接新建一个1.reg的文本文件,将以下代码copy 保存,双击执行便可。shell

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Prefs]

缘由:eclipse

Well i can answer that one: java.util.prefs.Preferences default implementation on Windows saves User Preferences AND System Preferences to the Windows Registryspa
