    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 : A problem occurred while processing the request. Please check our bug tracker to see if a similar problem has already been reported. If it is already reported, please vote and put a comment on it to let us gauge the impact of the problem. If you think this is a new issue, please file a new issue. When you file an issue, make sure to add the entire stack trace, along with the version of Jenkins and relevant plugins. The users list might be also useful in understanding what has happened.

    When you have no build parameters, uncheck 'This build is parameterized'
