I encountered an issue\bug with a new project.
I am using Jenkins 1.650 and 1.642.2 on different hosts but the result is
the same on all of them.
When marking the "This build is parameterized" in a Freestyle project
but yet to add parameters and starting a build, in the web interface I
am receiving some JSON java exception.
I have assumed that it should not crash but it does.
I would expect the build job to run even if there are no parameters defined for it.
Snapshots from the webui:
build page(without parameters) - http://snag.gy/loua2.jpg
exception - http://snag.gy/eZshW.jpg
Exception output after :
