Script to clean WSL and remove Ubuntu from Windows 11
Here is a fully automated PowerShell script that will:
-
Unregister and remove all WSL distros

Start Mule ESB as an NT service under a Windows server
Case
You would like to start a Mule ESB instance as an NT service, under a Windows server. You would also like to give a specific name and description
Fix
- add an environment variable
MULE_HOME
, with value the path of Mule install, for instance:C:\jonathan\mule-standalone-3.0.1
- edit the file
%MULE_HOME%\conf\wrapper.conf
- replace the following properties default values:
wrapper.ntservice.name=%MULE_APP% wrapper.ntservice.displayname=%MULE_APP_LONG% wrapper.ntservice.description=%MULE_APP_LONG%
- (you can also set other properties related to NT service configuration)
- launch the command:
%MULE_HOME%\bin\mule.bat install -config %MULE_HOME%\bin\mule-conf.xml
%MULE_HOME%\bin\mule.bat remove
Known issue:
On certain installations (among them the servers on which CygWin is installed), a conflict may happen between the files %MULE_HOME%\bin\mule
(standard launcher for Unix and Linux) and %MULE_HOME%\bin\mule.bat
(standard launcher for Windows). In this case, rename %MULE_HOME%\bin\mule
as %MULE_HOME%\bin\mule.OLD
sljava.dll / IntelliJ IDEA / ActivIdentity
Case
The administrators tried to install ActivIdentity on my desktop. Then I rebooted my computer and launched IntelliJ IDEA 8.1.4 as usual.
IDEA froze. I tried to launch former versions (8.0, 7.5.4), with the same result. Then I launched the idea.bat
(available in the same folder as the idea.exe
), setting echo on
, to have a little more logs.

Explanation and Fix
I ran other Java applications, such as Eclipse and Mule ESB. The result was the same.
When you look at the stacktrace, you can see that sun.reflect.NativeConstructorAccessorImpl.newInstance0
calls com.actividentity.sso.javasso.awt_swing.JavaSSOHook
. This makes me think ActivIdentity intercepts Java calls, even of very low level, and checks them before executing them. I don’t know if compiled code of JRE’s jars is modified, or if some methods are inserted through a mechanism similar to AOP. Anyway, the fact is that ActivIdentity is always called, even though I doubt a lot that original HotSpot was designed to do so…
I tried to uninstall ActivIdentity, this had no effect. I looked in Windows regedit but I found nothing. I tried also to check the value of java.library.path
which, for Windows, points to Windows’PATH
environment variable.
Therefore, the only solution I found to fix the issue was to changed the JAVA_HOME
parameter (more accurately: the parameter IDEA_JDK
) from one JDK to another, in my case: from 1.6.0_01 to 1.6.0_18)
