Problem on machines with non-ISO default text encoding. I have a multi-platform
project which involves IBM OS/390, Sun's and Windows Systems. I use JSSE for the
communication, works fine except for OS/390 where the default encoding is not
ISO.

If both partners run on OS/390 the SSL connection works fine, I suppose as the
same encoding is used the error neutralizes itself. However if one partner uses
ISO encoding (Sun or Windows) and the other uses another default encoding (IBM),
the SSL connection gets an error "javax.net.ssl.SSLException: bad handshake
record MAC".

I suppose somewhere in the SSL handshake protocol, text is converted from bytes
to unicode and vice versa using the default encoding. This produces the
mentioned error when the default encodings on the systems are different.

I think the encoding of certificates is fix and is ISO-8859-1, JSSE should use
the encoding name "8859_1" when converting text and not the default platform
encoding.
