Hi,
I finally found the culprit of a long running problem with Jenkins tasks
failing for windows build.
We had the server failing on partition tests on windows due to some
files that weren't able to be deleted at the end of tests. This was due
to some file handler not being closed properly. The difficulty was to
find out which of those handlers weren't released. Thanks to one of my
friends, I was able to track them. I used this tool :
http://file-leak-detector.kohsuke.org/
The simplest way to leverage it is by adding -javaagent:/<path to the
jar>/file-leak-detector-1.13-jar-with-dependencies.jar=dumpatshutdown
into the test VM arguments, and you get an output like this one :
File leak detector installed

Check all the open descriptors, and you'll be able to find out the culprits.
Directory Server jenkins build is now green for windows :-)
Happy Xmas !
