Unhandled event loop exception on TestNG plugin .8

[Thomas Fišer]

Hi Cedric,

When running the plugin, currently I get the following exception quite
regularly, could you please look into it?

Hope the stack trace is useful to you.

Cheers,
Thomas

Hi Thomas,

I've never seen this error, but I can fix it.

However, it seems to happen only if the main view of TestNG could not be displayed, so I think you might find another error if you scroll up in the logs. Let me know if you find anything interesting.
