I have a mac same problem. I open it up and nothing happens. I installed the latest java from the oracle website. Not sure if there's any error logs or something I can look at.
Found logs

Edit:
Discovered the jar file inside the .app file. Just used the .jar directly without trying to use it in the mac wrapper. Works fine in that case.
