Your frustration is understandable -- it must have seemed like Derby was 
doing nothing else today but looking at logos.

I suspect the real reason for silence on the issue you posted was nobody 
immediately recognized the problem given the information provided. The 
turnaround for a given problem often depends on if someone has 
encountered it or something similar before.

Did you try running the same query in ij? and did it get the same error?
