Tim Ellison commented on HARMONY-42:
------------------------------------

Paulex,

I don't understand this issue.  The file you have attached is a modified 
version of the com.ibm.platform.IFileSystem.java that is in NIO. Your comment 
indicates that it is enhanced to support regular IO types, yet it appears that 
mmap is removed.  Is that right?

I'm not going to take this enhancement at the moment.  Please provide further 
rationale.

(Please can you send your enhancements as diff's rather than file replacements, 
it will make tehm much easier to evaluate.)

Thanks,
Tim

> Many functions of FileChannel, such as memory map, transfer, 
> gathering/scattering I/O are not implemented. Further, three classes in 
> java.io, FileInputStream FileOutputStream, and RandomAccessFile, are related 
> to java.nio.FileChannel, so that they can be refactored to base on same JNI 
> interface, just like the network channels and sockets.
