But I doubt you aren't doing this. So, there is a command being created as a side-effect some other way. You could help by putting a breakpoint in IsisTransaction#addCommand, and - after a flush has been executed earlier in the stack trace - seeing why it is being called. If you're unable to do that / not sure how, we could arrange a remote debugging session this week some evening; it would be useful for me to know why this is occurring. In the meantime, the fix I'm putting in ISIS-533 might address the issue, whatever. Let me know.
