RouteConverter and Mac OS X

[hvdwolf]

I used "java -XstartOnFirstThread -jar RouteConverterPrereleaseMac64.jar".

Are you sure you've used the 64-bit version, the error message claims it had been the 32-bit version:

Yes, I see that now but I really used the RouteConverterPrereleaseMac64.jar. I'm affraid you packed a 32bit library into the Mac64.jar.
Especially as the folder "/var/folders/+R/+RmeG2o8EleS+UbdOPEbWE+++TI/-Tmp-/swtlib-32/" has been updated this evening whereas the swtlib-64 was updated yesterday evening.

And does the log contain something useful?

No, the same as the lines already in my previous post.
