I'm encountering an issue when trying to connect to the fdc3client using `fdc3Client.connect` ([line 185 in the example](https://github.com/openfin/java-example/blob/master/src/main/java/com/openfin/desktop/demo/FDC3Example.java#L185)). This never gets to either the `onSuccess` or the `onError`. I ran into the same issue when trying to run the example. I was later going through the docs [here](https://developers.openfin.co/docs/getting-started-fdc3), and I found the following wrt JS:\r\n\r\n\u003e Enabling FDC3 is as simple as adding it to your application manifest.\r\n\r\nTherefore, I created a quick test JS app, and added `\"fdc3Api\": true` to my manifest.\r\nNow my Java app works, since the FDC3 service has been launched and my Java app is able to connect to it.\r\n\r\nAs such, I am now looking for some way to enable the FDC3 service directly in the Java app. I have found references in the .NET API to enabling FDC3 ([here](http://cdn.openfin.co/docs/csharp/latest/OpenfinDesktop/html/1DF280C2.htm) and [here](http://cdn.openfin.co/docs/csharp/latest/OpenfinDesktop/html/6328E454.htm)), however have been unable to find anything of the sort for the Java API.\r\n\r\nAny help would be appreciated, thanks in advance.\r\n\r\n------------------------\r\n\r\nThe below is an excerpt of my code.
