That certainly does make sense, although it makes me wonder how this ever passed in the first place.  Maybe there's a bug somewhere in the JDB output processing code that made the failure intermittent.  In any case, it should be resolved now.  Thanks for doing the heavy lifting on investigation and debugging here.

I did have another question related to these tests.  I used a record class in the implementation of the `list003` test and I since learned that that's a preview feature.  Should I rework the test to avoid using record classes in case the feature is dropped later?
