I have a build job with multiple Active Choices Reactive Reference Parameters.

If the Choice Type is set to either "Formatted HTML" or "Formatted Hidden HTML" the parameter value is supposed to be passed to each build step as an environment variable.

The problem is that the value passed has an extraneous comma (",") at the end of it. For example, if I set the value of parameter "FOO" to "BAR", the value passed to my build step is "BAR,".
