A DESCRIPTION OF THE REQUEST :
The current implementation of MappedByteBuffer imposes a 2GB maximum size limit even on 64 bit machines with operating systems and physical memory that could support larger sizes.
JUSTIFICATION :
The 2GB limit prevents Java applications calling MappedByteBuffer from taking advantage of the large memory available on 64 bit platforms.
