Running server in command prompt, and its spamming endless empty lines, I do have the "Single bock anti-enderman griefing" thing, but command block logging and output are off.

attached is direct copy of console output, starts BEFORE a player connects and doesnt stop until after last player disconnects.

Any Ideas? could it be one of the java arguments (included in log file)?
