Does this means that the client needs to use a different serialization
infrastructure than the one provided by the JDK?

It would be nice if a client using regular JDK APIs and hence encodings
could talk to a highly performant MINA server. This is particularly
important for small clients, RMI implementations and such.

Same for the pascalStrings are they compatible with what read/writeUTF
produces?

You'll need to override read/writeClassDescriptor() method in
ObjectInput/OutputStream, and there will be four-bytes header which
indicates the length of the object. This is easily done without much code.

Yes, if you use a 'UTF-8' CharsetEncoder.

HTH,
