Jenkins is running on a windows 2003 server
In the job config postbuild task part:
log text : .
script : dir
When the job is successed or failed, the postbuild task works fine

When the job is aborted (manually stopped or timeout case) I get this kind of logs:
Running script :dir
[workspace] $ cmd /c call C:\Users\XXX\AppData\Local\Temp\2\hudson13287273761205392.bat
Exception when executing the batch command : null
Build step 'Post build task' marked build as failure
Finished: ABORTED

C:\Users\XXX\AppData\Local\Temp\2 is the java.io.tmpdir data

I ran a non-stop script listing files in this folder, the temp script
hudsonxxxxxxxx.bat is never written in this folder

in the jenkins log I have a java exception generated each time a job is aborted :
java.lang.InterruptedException

It is a main issue in my professional project.
From my web research it appears that post build task is supposed to work fine even when the job is aborted
