Yes, I follow both projects (superficially). I tried running my code
under Mono, but their Reflection.Emit code isn't ready yet. I haven't
tried the dotGNU code.

I use Managed C++, so JNI will only work on Microsoft's implementation.
Pure Java should eventially work on Mono (and possibly dotGNU) as well.
I don't use JNI for the classpath native code, but instead reimplement
the native methods in C# using the .NET framework.

I discovered a more serious problem with the current file i/o
implementation and I rewrote FileDescriptor, FileInputStream,
FileOutputStream & RandomAccessFile. The original implementation has a
problem with "ownership" of the handle. Since it is possible to get the
FileDescriptor from a FileIn/OutputStream it is possible to close a
handle, yet still have a stream that "owns" that handle, this is a big
problem. I fixed this by moving the ownership of the handle to
FileDescriptor (and all the native methods as well).
