Hello -

Just an FYI. I had an odd crash after adding some unit test code to an application. I have found the work-around for the problem but have not yet determined the cause. I got an exception on first accessing the app:

*Error:* java.lang.IllegalArgumentException: <com.webobjects.appserver._private.WOComponentDefinition> Class 'Main' exists but is not a subclass of WOComponent. *Reason:* <com.webobjects.appserver._private.WOComponentDefinition> Class 'Main' exists but is not a subclass of WOComponent.

The fix was to remove this jar from my project: selenium-server-standalone-3.14.0.jar

Oddly, the app ran fine while I was running in eclipse. But when i built with the included build.xml and 'Run as Ant', that application would crash, both on my Mac (dev system) and on Ububtu (my deployment). I have not made any changes to the default buils.xml. I confirmed the classpaths were properly constructed and everything pointed to existed and was readable.

I did not even remove the code that uses selenium. I just do not invoke that code and it is fine.

Anyway, just weird. If anyone know how this selenium jar is souring the soup, I would be interested in any suggestions.

This may not be a very important problem. On the other hand, when there is a problem and the symptom does absolutely nothing to point to the source of the problem, I find it interesting.

cheers - ray
