After installing plugin, getting compile errors and NoClassDefError for MoreUnit classes when viewing .js file

[davidmichaelkarr]

Today I installed this plugin, and when I tried to display a .js file for an existing project, I see two different things happening.

I'm getting somewhat odd compile errors displayed in the code view.

Here's an initial view of what I see in one file:

Here's what I see when I hover the mouse on the first red mark:

When I hover the mouse on the second red mark, nothing happens.

In addition, when I first displayed the file, I saw a couple of separate error dialogs reporting NoClassDefErrors for classes in the MoreUnit plugin. The following is from the error log:

!ENTRY org.eclipse.core.jobs 4 2 2018-10-28 17:24:36.656
!MESSAGE An internal error occurred during: "Update MoreUnit Annotations".

at org.moreunit.annotation.MoreUnitAnnotationModel$1.run(MoreUnitAnnotationModel.java:179)
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:63)

Any ideas what might be happening here/

In addition, I tried picking a line in this code and trying to remove the reference after the dot and seeing how completion works. This may be a completely separate issue, or maybe all of these problems have a common cause. In any case, when I tried to delete the "logger" reference in the following picture:

I then produced an error dialog, saying it wasn't able to build completions. In the error log, I saw this:

After a little more examination, I'm guessing this has nothing to do with this plugin. I didn't try to open a file in the project until I'd installed this plugin. If I had opened the file before installing the plugin, I think I would have seen exactly the same errors (perhaps not the MoreUnit error)
