Java needs an immutable byte array wrapper

[Keith Turner]

While trying to design an API for Fluo, its become clear to me that
Java could really benefit from an immutable byte array wrapper.
Something like java.lang.String except for byte arrays instead of char
arrays.  It would be nice if this new type interoperated well with
byte[], String, ByteBuffer, InputStream, OutputStream etc.

I wrote the following blog post about my experiences with this issue
while designing an API for Fluo.

Is there any reason something like this should not be added to Java?

Thanks,

Keith
