I have a top level job X. In X, I am using kicking off job Y using the File Parameter Factory option in parameterized builds. The configuration files contain a property, axis_values, which is a space separated list of different axis's for job Y.

Let's say that job X has one configuration file and it contains axis_values=A B C. I kick off job X, which in turn kicks one instance of job Y. Job Y iterates correctly through A, B and C.

Next, I change the configuration file and I set axis_values=A B C D E. I kick off job X and job Y starts. Job Y runs correctly for A, B and C. But, job Y fails to run D and E. It says that "D appears to be cancelled" and "E appears to be cancelled".

I see the following in the log:

31-May-2013 3:57:48 PM hudson.model.Executor run
SEVERE: Executor threw an exception
java.lang.NullPointerException
at hudson.model.Executor.run(Executor.java:238)

The only workaround that I have found is that it will work correctly if I put the new values at the start of the axis. (ie. axis_values=D E A B C)
