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.
這是一個warning,雖然不影響使用,但做爲一個有潔癖的人怎麼能容忍!java
解決方案以下:node
regedit
into the search field.HKEY_LOCAL_MACHINE\Software\JavaSoft
New
-> Key
Prefs
and everything should work.偷懶的同窗能夠直接新建一個1.reg的文本文件,將以下代碼copy 保存,雙擊執行便可。shell
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Prefs]
緣由: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
