null pointer when using TestNG in a matrix plugin

[Brian Mingus]

Hi,

I am running Jenkins 1.532 and TestNG Results Plugin 1.5. 

I have a job with a Publish TestNG Results Post-build Action where the TestNG XML report pattern is **/*/testng-results.xml and this works fine.

I am migrating to a matrix job and I now have the Any Build Step Plugin and Conditional Plugin installed. Together these allow me to call the TestNG post-build step as a build step. i.e.,

- Build

  - Conditional Steps (multiple)

    - Run? (Or)

      - ...

      - Steps to run if condition is met

        - Archive the artifacts

        - Publish TestNG Results

This results in the following stack trace:

00:16:16.366 Strings match run condition: string 1=[win], string 2=[mac]
00:16:16.450 Strings match run condition: string 1=[win], string 2=[win]
00:16:16.450 Run condition [Or] enabling perform for step [BuilderChain]

I've noticed that this is similar to the following issue:

https://issues.jenkins-ci.org/browse/JENKINS-11717

I have checked the encoding of the xml as per that bug report and that is not the problem, although I knew that because it works in the non-matrix job.

This error seems to be due either to the matrix job, or the Any Build Step plugin.

I will investigate more tomorrow. In the meantime, if anyone has any input on this issue I would appreciate it.
