While executing a former properly working build, I'm getting the following exception (please see one of the conditions below in the screen shot):

org.jenkinsci.plugins.tokenmacro.MacroEvaluationException: Invalid identifier in macro

The problem is gone as soon as I step back to the former version of this plugin.
