./bin/dspace oai import process deletes requests directory

[Steve Michaels]

I've discovered that when the ./bin/dspace oai import process runs, it doesn't just clear the requests cache, it deletes the ./var/oai/requests directory itself.

Is there a configuration that I'm missing, a command flag in the crontab command that's wrong ("$DSPACE/bin/dspace oai import > /dev/null"), or is this a weird bug?
