Projects files use VM-specific encoding, so they can't be used across 
different types of VM :-(

An ImageSegment is a WordArray whose contents are a sequence of heap 
objects in the VM's native object format.  A segment is loaded by 
invoking a primitive that swizzles the pointers in the word array so 
that they become valid objects, and then shortening the word array, 
leaving the objects behind in memory.  Since the contents of the 
WordArray are specific to a given VM architecture one cannot use the 
primitive loading mechanism to load segments from VMs with different 
object representations.

I am confused with the first statement. segment in ImageSegment is byte 
indexed and ByteArray has support for endian read/writes. Is there any 
reason why WordArray was used instead of ByteArray?

HTH .. Subbu
