Jenkins 2.46
Git Parameter Plug-in 2.4.5
Git Plugin 3.3.0
Git Client plugin 2.4.5
I see the following error frequently in /var/log/jenkins/jenkins.log
Aug 15, 2017 10:27:06 PM net.uaznia.lukanus.hudson.plugins.gitparameter.GitParameterDefinition getDefaultParameterValue SEVERE: nullUnexpected error! java.lang.NullPointerException
I assume this is occurring because I did not set a default value for the Git Parameter on many jobs. A default value should not be required, or a missing default value should at least be handled better.
The exception is probably being thrown here:
[JENKINS-46216] Null Pointer exception when no default parameter provided
I've updated the environment with more versions. I'm not really sure how to get more of a stack trace, since the Jenkins logs just show the message I posted above (around every 10 minutes).
My understanding of 44087 is that the exception would occur if a job was never built. That is a possibility in my case, however I don't know why this would be causing an exception so frequently. And I'm also not sure which build would be causing this (since there are many jobs on our Jenkins server that use the Git Parameter plugin.
Code changed in jenkins

Hi mksmith
I was change a way to get the job name, this should eliminate 'null' in log.
In Jenkins log you should have full stacktrace eg.

Hi mksmith,
Can you add some more information about your environment (versions of: Git client plugin, Git plugin, Git Parameter Plug-In) and more logs (mayby you have full stack trace)
Default value is not mandatory.
Please look at this issue JENKINS-44087. Is not this the same thing?
Regards
