Java Question

Java user.home is being set to %userprofile% and not being resolved

Our company recently upgraded from Windows XP to Windows 7 Enterprise. The JDK installation is no longer setting user.home to the full path of the user directory, but instead is setting user.home to

%userprofile%
. This is causing a lot of issues with applications such as Eclipse, Maven, etc. I now have to set -Duser.home in the JVM for each application. Has anyone else experienced this? Is there a fix for this? Would this be related to the installation of Windows 7 Enterprise? I have tried the 1.5 JDK and the 1.6 JDK.

Here is the list of properties. Note user.home:

Update:

Using the link to the bug from Andreas_D I discovered:

The value of
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Desktop
is %userprofile%\Desktop on my installation of Windows 7 Enterprise.

When I change the value of this key to
C:\Users\politesp\Desktop
, my user.home resolves correctly. Any idea why this is happening?

Answer

The majority of the registry keys located at:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders

began with %userprofile%. I updated all of the registry keys that began with %userprofile% to begin with C:\Users\myusername. I verified on Windows XP that the paths are in fact hard coded and that %userprofile% is not used. The IT guys mentioned that the registry keys defaulted to use %userprofile% due to a default profile being used within Windows 7. The JVM expects the Desktop path to be hard coded. It will not evaluate environment variables.

You can update the registry keys one by one or you can export the folder out and change the keys. Here is how you can export and import the registry keys:

1.  Go to Start > Run.
2.  Type regedit. This opens the registry editor.
3.  Browse to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders.
4.  Right click on Shell Folders and choose Export.
5.  Select the Desktop as the destination and enter Shell Folders for the file name and save the file.
6.  Open the file in a text editor and replace %userprofile% with C:\\Users\\yourusername. Save and close the file.
7.  Go back to the registry editor window and select File > Import from the main menu.
8.  Select Shell Folders.reg and click Open.
9.  Close the registry editor and delete the Shell Folders.reg file off of the desktop.
