Java FFI on Windows

[Bernard Devlin]

In the Extending Livecode part of the Dictionary it says:

*"Java bindings are currently supported on Android, Mac and Linux."*

I am at a loss to understand why Java extensions are supported on Mac and
Linux but *not* on Windows.

I've seen no explanation for this anywhere. Can someone enlighten me?  I'd
understand why Objective C extensions would not work on Windows, but Java?

Can extensions on Windows *only* be written in C?
