We have a ssh pre-build script set up that resets our test data on another box in our Jenkins instance before we then run our tests. However we noticed this morning that the job had failed during the pre-build section. However we did not get the email through from jenkins saying the build had failed. I'm guessing the whole thing crashed out so it never even attempted the email. Here is the traceback we received:

java.lang.NullPointerException

Is there a reason why this shouldn't email that it failed?
