Hide the DEFAULT CHARSET about iris-java

[paplorinc]

If I add it to the tests, I would repeat it's value. I have changed it to package private, since the tests use the same package.

Not really, because the encoding of the data blobs are completely irrelevant from Iris's point of view and are independent of the strings. In essence, the encoding used within the protocol and the encoding in the tests are semantically different things.

But package private will do just fine.

I can't rebuild the original String, if I don't know the original encoding.
But you're right, since I can compare byte arrays also, I don't need it in the tests.

[karalabe]

Yes, but what I meant, is that the data blobs concern the client of the library and not the binding itself. If the client wishes to put UTF-8 strings into the data blobs, so be it, if protobuf packets, then that is also fine.

I'm just saying that the two encodings (stings vs. the one used in the tests) are not tied together.

You're right, fixed it
