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,但作为一个有洁癖的人怎么能容忍!
解决方案如下:
regedit
into the search field.HKEY_LOCAL_MACHINE\Software\JavaSoft
New
-> Key
Prefs
and everything should work.偷懒的同学可以直接新建一个1.reg的文本文件,将如下代码copy 保存,双击执行即可。
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Prefs]
原因:
Well i can answer that one: java.util.prefs.Preferences default implementation on Windows saves User Preferences AND System Preferences to the Windows Registry
JRebel Windows RegCreateKeyEx(...) returned error code 5.
