Can't run OH2 as service on Mac OS X 10.11 El Capitan

My OH2 install loads just fine using, but not at all as a service. I used the command from the openhab console to install it as a service, and followed the subsequent instructions to move the plist to /Library/LaunchDaemons, and set the permissions etc., but when I load it with launchctl, all I get in the system log is
3/29/16 8:35:22.078 PM[1]: (openHAB[66663]) Service exited with abnormal code: 1
and nothing in the openHAB log.

As far as I can tell all permissions and ownership are as they should be. I found a typo in the plist, had an extra / in the path to openHAB-service, but fixing that made no difference. I’m not terribly familiar with launchctl, so I’m not sure where to start debugging this, especially as nothing is getting logged.
Mac OS is 10.11.3, OpenHab is the latest (as of 3/29/16)
