[Mono-list] NET using Java VMs and libs

Have you wondered *why* Java is still written in C/C++?. It has being six
years since Java's introduction, long enough imo for it's creators to have
moved from the C/C++ bootstrap to re-writing most of Java in Java itself.
Why haven't they done that?

Yet even before .NET was officially out, we already have projects like Mono
that are building .NET clones using .NET itself for the most part.

What is wrong with extending .NET to other platforms using the same tools -
i.e. C/C++/Asembler - that is used to extend Java to other platforms?.

It has already been pointed out to you that performance is an issue for
implementing .NET in Java. So also would be access to native platform
resources (for P/Invoke etc). Also, Java's designer's "purist" agenda has
hobbled the language in many areas for instance IMHO.

Write Once, Test Everywhere?

Why?. C# has it's own execution engine that is vastly more flexible than the
JVM. Imagine having to implement P/Invoke and COM Interop (or Bonobo/CORBA
Interop) in Mono if it sat atop a JVM......yuk!!!

So will C#/CLR.

Perhaps you really want a different project?. Kaffe perhaps?
