[Coco] Drivewire 4 vs. Java 9

[Mathieu Bouchard]

Sorry, two corrections :

I mean, "those that use DW4UI.sh"... you're on Windows, therefore (unless you 
install a unix kit) you don't have an interpreter for .sh files... I didn't see 
an equivalent ".bat" file. What you have to run is the .exe, but that doesn't 
seem to contain much more than the equivalent of a .bat file that does the same 
command as the .sh file. But that's just a deprecation warning.

The real problem, though, is the part about ClassCastException, which I forgot 
to read in your email, sorry. The only part where URLClassLoader is explicitly 
mentioned in the source code is at 
./DriveWireUI/src/com/groupunix/drivewireui/plugin/PluginLoader.java , which 
means any Java programmer (having Java 9.x) could take care of it on any OS (it 
does not involve recompiling anything platform-specific.
