Getting an error in Mule Debug perspective in AnypointStudio
<p>I am getting the following error when I choose Debug Project in Anypoint Studio:
Plug-in "org.mule.tooling.ui.contribution.munit" was unable to instantiate class "org.mule.tooling.ui.contribution.munit.runner.report.TestRunnerViewPart"</p>

<p>The full error I see in MUint tab:</p>

<pre><code>org.eclipse.core.runtime.CoreException: Plug-in "org.mule.tooling.ui.contribution.munit" was unable to instantiate class "org.mule.tooling.ui.contribution.munit.runner.report.TestRunnerViewPart".
