Sounds like a bug; afaik there shouldn't be any difference between Windows and
OS X here. :-/
Aside: JNIEnv.FindClass() takes a JNI type signature, not a Java one, so this
should instead be:
IntPtr JSInterface_Class =
JNIEnv.FindClass("com/fswidgets/jsinterface/JSInterface");
i.e. regex s#\.#/#g.

That doesn't make any sense at all. :-/
I would love to have a bug report with this code attached so I can investigate.
Thanks,
