Sponsor Request: Running jtreg plugin can fail with NoClassDefFoundError: com/beust/jcommander/ParameterException

[Jorn Vernee]

Hi,

When running a jtreg run configuration with the intellij jtreg plugin I 
am running into:

It looks like the jcommander jar is missing from the runtime class path. 
Following change fixes it for me [1]. I've also added the jcov jars just 
in case, since they ship with jtreg, and might also be needed at some 
point, though the particular problem I'm seeing is fixed if I only add 
the jcommander jar.

Thanks,
Jorn
