Unhandled event loop exception in TestNG Eclipse plugin

[Brad]

When selecting "Convert to TestNG" in Eclipse, the plugin appears to
do nothing. Upon inspecting the Eclipse log, I see "Unhandled loop
exception" (stack traces below).

Running Eclipse Indigo SP1 and TestNG plugin 6.4.0.20120220_1049.

Any idea what could be causing this? With thousands of JUnit tests to
convert, this feature would be a lifesaver.

Thanks!

Hi Brad,

Could you send me the JUnit class you're trying to convert?

Thanks.

Actually, never mind: I just fixed the problem.

Can you update your plug-in and report back?

Thanks!
