Batch processor log file garbage on startup

Classic Servoy
1

When Servoy Server is started up with a batch process solution, a stacktrace of the server log lists some exceptions that I can’t decipher. The errors only show up on startup – specifically when either addCronJob or addJob functions are hit on the startup method. The block of errors don’t repeat if multiple jobs are fired up in the startup method – always just one block.

However, the batch processes all work fine so I am not too concerned. For kicks, anyone know what the following means?

(Servoy version 2.2.5)

Figured out the trigger of the exceptions. My batched method did a search on a form that had a blob field on it in table view. Is it a correct assumption that a batch processor is a headless client? and that maybe headless client doesn’t like blob fields on forms in table view?

Short answer: Yep :)

The blobfields in HeadLess client errors is allready fixed for 3.1b4
