I am also encountering what appears to be same problem with the hp-application-automation-tools-plugin. My console output is virtually the same, including the "Unhandled Exception" stack. I am also running the 2.0.2 version of the plug-in, and LoadRunner 11.52.
The one difference in my Jenkins slave, is that it is running the Windows Server 2008 R2 Enterprise SP1.
I have verified that LR Scenario is functional, running it both interactively and via .bat file with the wlrun.exe command line options.
