As you can see, it seems like it's trying to parse the Java version number and failing.

This is the version of OpenJDK which comes with Ubuntu 16.04. This may be a bug in the copy of Processing which is embedded in it, I don't know. I tried to get it working from source using the latest Processing - it does - and then generate a newer version using Export Application but I haven't got that working yet - my exported application crashes for a different reason.

I will take a look at this. Please run from within Processing, if possible, in the meantime.
