RouteConverter and Mac OS X

[routeconverter]

Caused by: java.lang.IllegalStateException: An error occurred while creating the SWT Display! On a Mac, the Native Interface can only be initialized from the main thread and the Java process needs to be started with the "-XstartOnFirstThread" VM parameter.

Please download and start again with

java -jar RouteConverterMac.jar

and with

java -XstartOnFirstThread -jar RouteConverterMac.jar

I'm very interested in the console output - especially if it starts with "Before ...."
