JENKINS-14483 Remaining Xvfb processes in matrix jobs

implemented as kindly suggested by Chris Jonhson on jenkins-dev mailing
list

https://groups.google.com/d/topic/jenkinsci-dev/KQVDCV9ATm8/discussion

Thorsten, Chris Johnson helped me a great deal on the jenkins-dev mailing list (https://groups.google.com/d/topic/jenkinsci-dev/KQVDCV9ATm8/discussion) so I'm pretty confident that the version I've uploaded to Dropbox, finally, solves this issue. Now Xvfb is launched only for individual matrix jobs and should terminate and clean up when the job finishes. If I may be so bold to ask you to test on your end one more time, so that when you confirm that it's OK I can release version 1.0.4.

Thank you!

Hi Zoran, this is the error message (in matrix job) after installing your latest snapshot version:

Started by user Thorsten Kahler
[EnvInject] - Preparing an environment for the job.
[EnvInject] - Jenkins system variables are kept.
[EnvInject] - Jenkins build variables are kept.
[EnvInject] - [ERROR] - SEVERE ERROR occurs: null
Finished: FAILURE

This might be a compatibility issue with our outdated Jenkins version 1.434?

I'm guessing that env-inject plugin catches NullPointerException (probably here: https://github.com/jenkinsci/envinject-plugin/blob/master/src/main/java/org/jenkinsci/plugins/envinject/EnvInjectListener.java#L60), this could be due to setup method of xvfb plugin now returning null (https://github.com/jenkinsci/xvfb-plugin/blob/master/src/main/java/org/jenkinsci/plugins/xvfb/XvfbBuildWrapper.java#L255) on non unix platforms. Can it be that one of your slave is non-unix (windows)? It would probably be better for backward compatibility that the xvfb plugin does not return null on non-unix platforms, as it did in previous versions. I'll make that change and upload a new version on dropbox in a few minutes.

return empty environment instead of null from setUp method

Thorsten, I've uploaded a new snapshot on Dropbox, if it's OK now I'll release 1.0.4 later this afternoon.

Hi Zoran, still the same error.

fix NPE with Environment Injector Plugin installed

Hi Thorsten I was able to reproduce your problem with Environment Injector Plugin installed, luckily it was a very simple fix, and as usual I need your help testing the new version I've just uploaded to Dropbox.

Thank you

fixed in 1.0.4, changes in behavior are noted in the wiki (https://wiki.jenkins-ci.org/display/JENKINS/Xvfb+Plugin)
