Java doesn't have pointers, so right off the bat there'd be big
problems.
Java does have pointers... you just can't get to them easily. At
the very least, you could allocate and manage your own chunk of
memory and do all the pointer arithmetic yourself on that chunk.
This would require the chunk to be pinned in some way and the GC
to be turned off but it is an option.
Also, have you looked much at sun.misc.Unsafe?
Or maybe one could use the JNI to write an external memory
manager for each platform and all pointer arithmetic is passed
through that. Of course, if one goes this far then any "javaD"
would need to be able to work well with importing java libraries
to be of any use.
