Java main() method does not run from right-click, but does run from Run Configurations [message #641186]

If I right click on a class with a main() in it and choose Run as Application (or Debug) I get an error message "Editor does not contain a main type."

But when I go to Run Configurations and manually create a configuration for it, the class does run.

I confirmed that this class is in the source path for the main codebase of the project (as opposed to test classes).

Interestingly, other classes, in the test source-path for the project, do run from right-click.

What could be causing this?

Where (editor, Package Explorer, ...) do you right click? If you can
provide steps then please file a bug report against JDT Debug.

The bug occurred both from Package Explorer and from the main body of the Editor. It occurred for both Run and Debug.

In addition, Find References for any method would always find zero references; though the feature worked for classes.

Also, an attempt to refactor, e.g., a method signature, caused an error.

I built a completely new workspace from my SCC and so managed to work around the problem.
